The Tramfabriek Allrounder© chassis is a development of many years building chassis for small box style locomotives. I was looking for the smallest and best solution, that would give great running capabilities at slow speeds and be quiet. One of the downside of the commonly availably (often Japanese) small chassis, is that the motor often drives the wheel axle, which causes the chassis to behave like a Mini Cooper at Brooklands race track (before it closed down). Another classic problem is that you have limited connection options to the frame of the model loco, as often the available drives were made to click in the own models of the manufacturer. The Tramfabriek Allrounder addresses all those issues.
16 mm wheelbase with 8mm wheels
Features
Coreless Motor
Popularised in the model train market by the Tramfabriek for a very good reason: these little 12V coreless motors are brilliant. Quiet, low current use, no snapping and staying cool. Used with proper gearing, you really get the best out of them. RPM is around 11,000 rpm.
RP25 Wheels
The Allrounder© is available with 7, 8 or 9 mm RP25 wheels, which means it has slim, more realistic flangs than traditional “pizza cutters”. From wheelbase 17mm and up, 10.5 mm and 11mm wheels can be chosen.
Proper Gearing
Not saving on quality gears, gives this chassis smooth running at every step. Excellent slow running, but also a more realistic maximum speed for small models.
Several ways of connecting to model
Every model locomotive is different, so for each project you can decide how to connect the drive to it. The Allrounder© has many ways to choose from with the innovative and flexible Height Wings. All the different ways are displayed further on this page.
Brass bearings and steel pins
On the axles there are brass bearings and the gears run on steel pins, to assure stable, reliable and durable running.
The Allrounder© comes in three versions
- The A version is comes in wheelbases 15 to 30 mm.
- With Centre, Corner and Front Wings, so you can connect your drive in many different discrete ways to your model.
- Centre Wings adjustable with a screw
- Front wings need to be glued
- The C version is comes in selected wheelbases.
- With Centre and Front Wings, so you can connect your drive in many different discrete ways to your model.
- Centre Wings adjustable with a screw
- Front wings need to be glued
- With coupling rods
- With flywheel (can be left out on request. A motor with one shaft can be fitted)
- The F version is for longer wheelbases, up to 47 mm. Other size between 40 and 47 mm on request.
- When space allows, the coreless motor will sit lower than on the A version.
- Front Wings, adjustable in height with a screw.
- No Centre nor Corner Wings
- Flywheel (10x3mm) only on Allrounder with wheelbase 37 mm and longer.
Example: wheelbase 17mm, Ø 8mm wheels
Example: wheelbase 16mm, Ø 8mm wheels
Example: wheelbase 40mm, Ø 8mm wheels
* Please note that a set of all wings are supplied with every Allrounder© A and C, but the screws of the Corner Wings are optional, in order to avoid waste when people don’t need them.
The length of the Allrounders is depending on different factors and not all wheelbases have been designed. If you need accurate information, please ask me.
The unique Allrounder© feature: Wings
There are many ways possible to use the wings. You can use only the centre wing, only the front wings or only the corner wings. Or a combination of it. You can screw the chassis to your model, or with a little bit of glue.
Three different sizes of Centre Wings are supplied. Select the one that fits in side your model.
Included with one Allrounder© A
- Complete chassis, ready to run.
- 8 Centre Wings (2x L, 2x M, 2x S)
- 2 Screws (5mm long) and 2 bolts M1.6 for Centre Wings
- 4 Corner Wings
Included with one Allrounder© C
- Complete chassis, ready to run.
- Coupling rods and flywheel fitted.
- 8 Centre Wings (2x L, 2x M, 2x S)
- 2 Screws (5mm long) and 2 bolts M1.6 for Centre Wings
- 4 Corner Wings

- 2 fitted Front Wings + 2 spares.
- 2 Screws (5mm long) and 2 bolts M1.6..
Sizes
Any other wheelbase will have the same dimensions, just add the difference to the length. So the chassis for a 20.7 mm Allrounder© will be 4.7 mm longer than one with a 16 mm wheelbase (20.7-16=4.7).
Centre Wing Size L
Height Wings
Centre Wing Size M
The length of the Allrounders is depending on different factors and not all wheelbases have been designed. If you need accurate information, please ask me.
The body width, like with all Allrounders, is 6.4 mm.
Front Wings
Centre Wings
Corner Wings
Front Wings need to be glued at the correct height to connect the drive to the front and/or rear of the model. The slot in the chassis is for the guiding pin on the wing.
The screw of the Centre Wing (supplied) holds the contact strip in place, as well as the wing. It connects to a metal bolt inside the drive and the wing can be raised or lowered to the desired height, to support the model.
The horizontal bolt (also supplied) you see on the picture will secure the bottom plate of the model to the Centre Wing.
The Corner Wings can be used as extra support when the Centre Wing is connected to the bottom plate of the model. They can be used with or without screws. Or they can be the main support of the model, leaving out the Front and Centre Wings. The Corner Wings have a supporting platform, which can be turned inward or outward of the wheels. Or the platform can be cut off, if they only serve as additional support.
Wheels
All wheels are RP25. On top of the diameter choices, there are two different 9mm wheels. One is a Halling wheel, which is a bit thicker and less detailed. The other is a slimmer, more detailed wheel.
Plain 9mm wheel
Thickness 2.5mm
Detailed 9mm wheel
Thickness 2.2mm
There are also very nice 10.5 and 11 mm wheels. There is a surcharge for this, as they are quite more expensive to purchase than the smaller wheels. They will add a good splash of realism to your model.

Bogie version
There might be a bogie version. The problem is that many of you have your own specifications and the work involved is not something I can handle time wise. At the moment I can only do this for small manufacturers.
Maintenance options
Maintenance cradle
The Allrounder© chassis has an awkward shape to lay on the table. This maintenance cradle I mainly made to make the work on the drive easier for myself. For those who like to have a copy of it, I have made it available. What I did myself was to stick the flat bit with double sided tape to a bit of thick cardboard, so the cradle can be held in place. You can turn the cradle around and stick the other side on.
Here two examples on how it can be useful.
Screwdriver
The screws used in this chassis are M1.2 and M1.6. Not everybody has a screwdriver for that size, so you can purchase this here. Included is a small magnet, to clip on the screwdriver. This way it becomes magnetic and makes it easier to fit the screws. The diameter of the head of this Phillips screwdriver is 1.5 mm, in case you want to check with what you’ve already got.
Allrounder-X - For the small manufacturer
If you are one of those many designer of 3D printed model trains who is looking for a good chassis for your model, then the Allrounder© might be something for you and your customers. Contact me to talk about custom solutions. Changes to the chassis with different wheelbases or custom connectors can be made on request. You can either let your customer order from me or order a batch from me for discounted prices.
DCC fitting
Fitting DCC is very easy. Just desolder the red and blue motor wires, no need to take apart anything else. Then solder the orange and grey decoder wires to the motor wires (or, if you feel brave, solder the motor wires directly to the decoder). The red and black wires from the decoder are soldered to the phosphor bronze wheel contact strips for track power. Remember when soldering: quick in, quick out. The chassis is made of plastic, so it would melt if you touch it or linger on the contacts too long. Luckily you have been given extra Height Wings, so you have a second and even a third chance if you mess up. On the picture you can see to what coloured cable of the decoder you need to connect the drive.
