Railway Motive Power

Battery Electric Shunting Tractor

I find small industrial locomotives from the early days of the railways fascinating, especially alternative power such as “fireless” and electric. This free-lance design for a battery electric shunting tractor takes cues from a variety of styles and simply fits over the Hornby 48DS chassis with no modifications to the chassis whatsoever. I have designed and printed a glazing set in clear resin - contact me for details. (May 2021)

QR DH Class Diesel Hydraulic Locomotive

My favourite locomotive, bar none, is the “DH Class” of early diesel hydraulic locomotives built by Walkers Ltd for Queensland Railways in Australia. I have fond memories of watching them shunt fruit wagons at the Golden Circle cannery at Bindha in the early 1980s. The QR locos are to 1067mm track gauge, although the design was adapted for the standard gauge 73 Class for the New South Wales Government Railways. Quite a few DHs still survive around the place, having been sold off by QR to new owners. Some have even been re-gauged to 610mm, 900mm and one-metre gauge. The model has been based on original drawings by Brian Millar, who has also generously provided lots of photographs and ancillary drawings. While the original file is to 4mm scale (OO), it scales nicely to HO and even TT on my Anycubic printer. I have included a HO version and S Scale version that I have re-scaled in the design software, but you can also re-scale the OO version in your printer. Note that the exhaust stack and horns are separate pieces and are really tiny - don't lose them when removing from the print plate! For my model (4mm scale) I am using a Black Beetle motor bogie, so the chassis and bogie sideframe are designed to suit. (May 2021)

Re-scaling ratios: OO to HO = 87.36%, OO to TT = 63.33%, OO to S = 118.75%.

QR AEC Railmotor (RM55 Red Fred)

Queensland Railways operated a variety of small railmotors. RM55 (known as Red Fred) was built in 1930, using a AEC petrol-powered truck/bus chassis. As built, it had open sides, but in 1938 the body was enclosed and the AEC petrol motor replaced with a 38 kW (50hp) 4 cylinder Gardner diesel engine. RM55 was based at Isis, then Fassifern and Beaudesert around the 1940s and 50s. By 1954, RM55 have moved to Townsville until withdrawn from service in 1966, being the last of its type in service. The 3D files have been created from a basic dimensional drawing and various photos. The floor cutout has been sized to take a Steam Era Models "Black Bug" power units, but you will need to figure out a front bogie. The roof print provides a basic profile, but you will need to sand/file the compound curve to a final smooth shape. (July 2021)

E.M.Baldwin DH 22B Cane Locomotive

My representation of an EMB B-B DH22B, a 22 ton diesel hydraulic locomotive built in 1973 by E.M. Baldwin & Sons (EMB) of Castle Hill, New South Wales, Australia. EMB had started out as a small engineering works specialising in stainless steel fabrication, but expanded into light industrial locomotive production after WW2, producing a family of locomotives that were common sights on Queensland cane railways. Individual locomotives underwent many modifications during thier lives, with changes to lights, cabs, and the fitting of more mdoern safety equipment. The DH22B locomotive was originally owned by Fairymead Sugar Mill, before being purchased by Bingera Mill, and finally ending up with Millaquin Mill, where it carried the name Calavos. The one-piece body is designed to be a snap-fit onto the donor chassis – a Bachmann N scale 44 Tonner which is a very smooth runner and comes fitted with DCC. No modification is needed to the Bachmann mechanism, so it can be converted back at any time. The roof, exhaust fairing, lights and horn are separate pieces to assist painting and assembly.

Climax Locomotive - B Class (Narrow gauge)

Climax Locomotive

Everybody loves a geared locomotive! The objective of this project was simple: take a common, reliable, smooth-running N scale mechanism and build a credible model of a HOn2.5 narrow gauge Climax locomotive around it. A geared loco for the average modeller. This would, of course, require a number of necessary compromises (including static cylinders) but the final result has all the key features of a Climax and looks the part. The Climax body is designed to fit over an unmodified Atlas N scale mechanism from a GP7 or similar – a quality mech easy to obtain new or second-hand. It is also available with DCC if desired, so no worrying about how to squeeze a decoder into the final model! The print is made up of a number of parts to aid painting and assembly. The buffer beams are designed to fit Microtrains N scale couplers. The mechanism unavoidably intrudes into the cab space, but if this area is painted matt black and obscured by crew figures, it is not too noticeable. I have modelled some overlays for the bogies that provide a very rough representation of a Climax trucks, but they disguise to some extent the modern Blombergs of the GP! They will need to be attached with contact adhesive of similar. On my model, I glued small slivers of wood over the bunker insert to represent the split-log fuel load, but coal could equally be used.

NER Inspection Car

NER Inspection Car

This project began when I wanted to create a chassis to hold a motor unit from a 1970s vintage Lima 0-4-0 diesel locomotive. Despite its age, 3-pole armature and deep wheel flanges, it’s quite a nice little runner, especially when more weight is added. The motor unit is compact, completely self-contained (all wheels collect current and are driven) and it can even be easily fitted with DCC. The 0-4-0 Lima locomotives are still fairly easy to come by second-hand. If I could create my own chassis to hold the motor unit, it would make a good basis for a variety of models. To test the concept, I looked around for a suitable body and found a 1:76 model on Thingiverse of a North Easter Railway Inspection Car created by Jason Liversidge (https://www.thingiverse.com/thing:3376888). The first one of these cars was built by the NER in 1908. Three more followed, although all were out of service by 1939. Although my chassis in no way resembles that of the real NER cars, the finished model does look cute. I had to make a few modifications to the original body to provide clearance for the motor unit and so it could be attached to the chassis. (May 2022)

Sentinel Tram Locomotive - Humpybong (Narrow gauge)

Sentinel Tram Locomotive - Humpybong

The Sentinel Waggon Works of Shrewsbury, England produced a range of steam-powered road and rail vehicles. Their distinctive locomotives had a squat boiler located in the cab (chimney protruding through the roof) and a compact vertical steam engine at the front (covered by a cylindical casing), driving the wheels via chains. Sentinel locomotives sported a number of different body and cab styles. My narrow-gauge model is reminiscent of LMS No 7164, built in 1931, above the footplate, with a tram-style plated-side chassis designed to take the mechanism from a vintage HO scale Lima 0-4-0 diesel (See the NER Inspection car model above). Although I am not aware of any narrow gauge Sentinels being built, it certainly looks the part. My design consists of the chassis, body, cab and buffer beams. The chassis has circular recesses to take four No 2 sinkers for weight. The buffer beams are designed to take Kadee HO scale standard couplers. I attached the body to the chassis with four 2mm x 4mm pan-head screws. The body has holes to take standard office staples as handrails. My loco has been named "Humpybong" (a name derived from the Australian aboriginal words meaning "deserted shelters"). Files are provided for a body with this name incorporated as well as a body with blank name plate. Similarly, there are files for a cab with number or with no number. (July 2022)

Sentinel Tram Locomotive - Gayundah

Sentinel locomotives came in various body styles, some looking quite modern and stylish. This version is based on a much later design, built in the 1950s and one of the last steam shunters to be built. Again, it is designed to take the mechanism from a vintage HO scale Lima 0-4-0 diesel. The model consists of the chassis, body, cab and buffer beams. The chassis has circular recesses to take four No 2 sinkers for weight. The buffer beams are designed to take Kadee HO scale standard couplers. I attached the body to the chassis with four 2mm x 4mm pan-head screws. The body has holes to take standard office staples as handrails. My loco has been named "Gayundah" (a name derived from the Australian aboriginal words meaning "lightning"). Files are provided for a body with this name incorporated as well as a body with blank name plate. Similarly, there are files for a cab with number or with no number. (July 2022)

This is a freelance design for a narrow gauge tram locomotive again designed to take the mechanism from a vintage HO scale Lima 0-4-0 diesel. My design consists of the chassis, body, cab and buffer beams. The chassis has circular recesses to take four No 2 sinkers for weight. The buffer beams are designed to take Kadee HO scale standard couplers. I attached the body to the chassis with four 2mm x 4mm pan-head screws.

Railway Rolling Stock

Shunters' Truck

Hornby’s model of the diminutive Ruston & Hornsby 48DS is an absolute gem. It runs extremely well; amazing given its tiny 0-4-0 wheel arrangement. Hornby provides a “match truck” with extra wheel pickups that can be electrically connected to the loco. This improves reliability even more. The supplied match truck is a fairly basic ConFlat wagon. I thought a shunters' truck might be more appropriate to pair with the 48DS. This free-lance design consists of only three pieces, a deck and two sides. It is designed to simply replace the existing ConFlat deck (which just unclips from the chassis). I drilled a hole in the centre of the chassis so I could run a fixing screw up into the toolbox which has a hole formed in it. (May 2021)

GWR Aero Wagon

The problem of transporting large 3-bladed airscews (aircraft propellers) was originally solved by GWR with the development of a wagon with a special cradle to support the three-legged airscrew crate. The opening in the deck was off-centre to miss the brake gear. By 1941, GWR had built over 170. Other Aero wagons were built by the other "Big Four" companies, but being a wartime design, were less sophisticated than the GWR design - often just a converted open wagon with a timber cradle. During the war, the wagons were pooled and by May 1944 the fleet had grown to over 700 wagons. My representation consists of separate pieces for the chassis, deck/cradle and crates. I've also included a one-piece chassis/deck/cradle file for the adventurous. The brake levers are fitted separately. The NEM sockets are also provided separately - I use a 1.7mm flathead screw to attach them, with a 1mm styrene rod attached to the rear of the socket to act as a self-centering "spring". Standard Hornby 12mm pinpoint wheelsets fit into the chassis - the bearing holes may need a bit of honing with a microdrill to get free running.(November 2021)

Queensland Sugar Cane Bin Wagon

The ubiquitous sugar can wagon can be seen on just about any cane tramway in Queensland. While there’s a variety of sizes and styles, most consist of steel mesh supported by a steel framework, mounted on a basic 4-wheel integral underframe.The model is based on a Moreton Sugar Mill 4-Ton wagon. This is a simple one-piece print with the axle boxes spaced for Atlas or similar 33-inch N-scale wheels. The mesh can be simulated with either a fabric gauze or fine metal mesh. (August 2021)

Buderim Tramway Passenger Coach (Narrow gauge)

Buderim Tramway Carriage

The Buderim Tramway was a narrow gauge (2' 6" – 762mm) 11.6 kilometre railway that ran from the Queensland Railways mainline station at Palmwoods east trough the undulating countryside to the Buderim Mountain Township. The railway began operating on 1 December 1914 and the last scheduled service was in August 1935. It was instrumental to the growth of the area during this time and carried just about anything that could be loaded onto a railway wagon. Only two steam engines ever worked the line, a Krauss 0-6-2 and a Shay. The railway possessed on passenger coach and one guards van. [ Read more about the Buderim Tramway ]
Little information is available about the rolling stock used on the Buderim Tramway. The few photos available are blurry and don’t show too many details. Legendary Queensland modeller, Jim Fainges, left a legacy of many drawings and models of narrow gauge railways and his sketch plans were used as the basis for this model of "Car No. 1" – the solitary passenger coach used on the line (although open wagons were also used on the odd occasion!). I have modelled a basic interior, but the seating layout is pure conjecture. The coupler recess has been sized for an N scale Microtrains item. The chassis has been designed for a N scale Green Max Brill bogie (Part No 5020) which look very similar to the bogies shown on the Fainges plan, however other N scale bogies should also work. I use fishing line to reproduce the truss rods, an old modelling technique. The roof vents are very, very small – I recommend printing a dozen of them as you will probably lose half at some point! The O scale version has a modified chassis to fit Kadee HO gauge archbar trucks. The truss rods are provided as a separate part - the truss rods print fine at the larger scale. (December 2021)

Buderim Tramway Guards Van (Narrow gauge)

Buderim Tramway Guards Van

My model of the Buderim Tramway’s only Guards Van is again based on a sketch plan drawn by Jim Fainges. Jim’s plans show some slight dimensional differences (which translate to fractions of a millimetre at HO scale) to that of the passenger coach body, but for the sake of expediency and consistency, I have used the same roof and basic body shape as the coach. Hopefully, history (and Jim) will allow me this use of modeller’s license. The part’s list and assembly are essentially the same as the passenger coach. The coupler recess has been sized for an N scale Microtrains item. The chassis has again been designed for a N scale Green Max Brill bogie (Part No 5020). Like the coach, the O scale version of the van has a modiifed chassis to fit Kadee HO gauge archbar trucks. The truss truss rods are provided as a seperate part - the truss rods print fine at the larger scale. (December 2021)

Mapleton Tramways Coach Guards Van (Narrow gauge)

Mapleton Tramways Coach Guards Van

The Mapleton Tramway was a narrow gauge (2' – 600mm) light railway that ran west from Nambour up the Highworth and Blackall Ranges to the mountain village of Mapleton. Its original intended purpose was to transport sugar cane to the Nambour mill. Construction began in 1897 and the line closed 31 December 1944. It operated small Shay geared locomotives and a motley collection of rolling stock. My model is of the "big" passenger coach with guards compartment. Various sketch plans were used as reference as well as a few blurry photographs. It has been designed to take Kadee HO gauge archbar trucks and standard couplers. (July 2021)

WW2 Concrete Air Raid Shelter

During world War 2, civilian air raid shelters sprang up everywhere, ranging from the DIY Anderson shelters to substantial concrete structures built by the authorities. This design is based on shelters built in Brisbane, Australia, erected in streets and around factories. A few still remain. There are two sizes. The large is approximately 80mm long, while the small is 70mm long. (March 2021)

Queenslander Worker's Cottage

The quintessential Queenslander Worker's Cottage is a small (usually 2 bedroom) timber-framed, timber clad structure with corrugated iron roof. Typically perched on stumps enclosed with timber battens, other spotting details include metal window hoods and decorative verandah brackets. The projecting galvanised metal enclosure off the kitchen housed the wood burning stove. Originally offered as low-cost housing for the masses, early examples were imported in kit form from the United Kingdom. in 1928, a basic house could be purchased for under 500 pounds. Larger and more elaborate designs were also offered for those who could afford it. Notwithstanding the rainbow palette seen today on surviving houses, original colour schemes were very basic - walls were a nondescript brown stain, stumps and battens were creosoted, roofs were plain galvanised and trim almost always white. This is a complex print, as can be seen from the number of files and not for the faint-hearted. It has been successfully printed on an Anycubic Mono X resin printer, however, you will need to be reasonably experienced with choosing print angles and creating (and removing) temporary support structures.

Queensland Shop

Shop

In the mid 1970s, my parents owned a small shop on Hornibrook Esplanade on the Redcliffe Peninsula. It was a general store and sub-newsagency, selling everything from smallgoods to bulk kerosene for heating. While the shop still exists (as a dog grooming saloon!), the original facade has been destroyed - the windows and doors replaced with roller shutters. My model is, therefore an amalgam of typical features found on such small freestanding shops. The detailed interior is, however, as faithful a recreation of our family shop layout as my memory allows, complete with the Coca-Cola drinks fridge. I have modelled three facade shape options to provide a bit of variety: stepped, curved and angled. The facade is quite delicate and prone to warping, so there are also "thickened" versions if you have trouble with the thin version. Similarly, the awning posts are not necessarily worth the effort in resin and can be substituted with strip styrene. (September 2021)

Queensland Railways Station

Station

The Queensland Railways "standard" station design was not always standard! Local variations seem to have been frequent, from type of cladding (weatherboard/chamferboard) to number and location of doors/windows. My generic representation is based on site measurments of Spring Bluff station, with elements of Petrie station incorporated. As well as a metal window hood, I have also included a wooden style as an alternative. I can't claim credit for the wooden version - it is a modification of the excellent one created by Luke Towan, well known for his ultra-realistic scenery modelling (www.bouldercreekrailroad.com) (October 2021)

Queensland Railways Cream Shed

Queensland Railways Cream Shed

Nothing says QR like the ubiquitous cream shed. The horizontal double slatted walls are very distinctive and it's difficult to imagine how they could be modelled easily without 3D printing. These small building were found throughout the state and their role often extended beyond their original intent, being used for the storage of all sorts of perishable and general goods. Some even survived as passenger waiting sheds or serving as the station building itself! This model is based on the official QR plan for a standard 10’ x 10’ shed with corrugated iron gable roof. Some sheds were built with skillion roofs or fibro "state" tiles were substituted for the corrugated iron. Included are two versions of the walls - one has the doors incorporated, while the other allows doors to be fitted separately, either closed or in an open position. Note that the original plan shows the doors opened inwards. The stumps should give a platform height close to the regulation 2' 6' above rail height, although shed platforms heights seemed to vary enormously in practice. (January 2022)

Queensland Railways Goods Shed

Queensland Railways Goods Shed

The Queensland Railways standard goods shed design came in three sizes and I have modelled the "medium" 20' x 30' version. They were clad in either weatherboard or vertical corrugated iron sheets, but I have used weatherboards to match the QR station. Photos show two main variations of door placement; a pair of centrally located side doors, or a pair of offset side doors and an end door. Loading platforms varied greatly, with some extending past the shed and mounting a goods crane. I have included files for the doors, but it would be easier to just use scribed sheet styrene rather than a resin print. (January 2022)

Precast Concrete Box Culvert

Precast Concrete Box Culvert

The humble concrete box culvert is often overlooked, yet they are used all over the world to provide cost-effective drainage solutions for roads and railways. They handle a larger water flow than pipes and are cheaper and faster to build than an equivalent bridge. They come is a variety of sizes and profiles, depending on manufacturer. My model is based on a 1200H x 1800W unit from Humes, an Australian manufacturer. It represents twin precast cells installed on a cast-in-situ base, wingwalls and parapet. The internal sections come in two widths. A complete model consists of two Outer/Wingwall sections and as many internal sections as needed to achieve the width you want. (March 2022)

WW2 Austin K2 N.A.A.F.I. Van

During World War 2, Navy Army Air Force Institute (N.A.A.F.I.) refreshment vans, run by volunteers, were a common site amongst the troops. This is a re-mix of an original model by "m_bergman" uploaded to Thingiverse, modifying the cab and chassis, making the wheels seperate pieces and creating a new body, complete with interior. It's to 1:100, but scales up to 1:76 OK on my printer. Not fine-scale, but looks the part. I added micro-LEDs for interior lighting and installed a "tea lady". (March 2021)

This is a fictitious (but plausible) low loader trailer version of the AEC Matador. The cab-chassis is based on the file by "Jeremycon" [https://www.thingiverse.com/thing:3330532]. The cab-chassis has been shortened considerably and the cab roof height lowered (the original file looked high when compared to an Airfix kit of a Matador). It was also "hollowed out" so windows and a basic interior could be fitted and a trailer hitch mount added. The trailer is not based on any particular prototype and has been designed with cradles to take two "Upkeep" bouncing bombs [https://www.thingiverse.com/thing:4552521] (July 2021)

LNER-Style Cast-Iron-Bracket Buffer

There are plenty of commercial buffers available, but for my shunting micro-layout I wanted something really compact. I came across photos of a old LNER style that had cast-iron brackets at the rear, bracing the headstock. Using this concept, I came up with my design that takes up very little space. It is sized so that when installed on the same base as Peco code75 track, it should be the correct height. The drilling jig allows accurate drilling of holes in the baseboard to take the attachment pegs. (March 2021)
