Wow, amazing detail in the file and thank you for the PDF of the ttc logo, bravo.

Hi Richard,

Do you know how your model compares to HO scale?


I assume you mean the body, as the wheels and trucks aren't designed to work on an HO track.

According to Wikipedia:

HO scale is 1:87 - https://en.wikipedia.org/wiki/HO_scale
The TTC H6 is 23M long - https://en.wikipedia.org/wiki/H-series_(Toronto_subway_car)

For an HO TTC H6 model, that means you'd want something about 26.4 CM long.

The OpenSCAD and STL files are 220 units long. If you're using Makerware, it will imports this as 220 mm.

For HO, you would want to scale the model to 120%. In Makerware, you can click on Scale and change the X dimension to 264 mm or set "Scale To:" to 120%.

Great, I appreciate your quick response, including additional details. Thanks very much!

Question for Raudette:

How do you integrate your H6 subway car with other rolling stock on a Brio Wooden train set. Specifically, we are looking for the magnets that connect one car to another. Brio won't talk to me. Earth magnets are way too strong. Outside of scavenging magnets from surplus Brio cars, I have failed to come up with a solution.

My wife and I have printed off two copies of your delightful H6 subway car for a four year old we know is crazy about TTC stuff and trains in general. The Star article inspired us to take the certification course at the reference Library in Toronto. Now I'm exploring open SCAD in hopes of printing up some replacement parts for my RC aircraft. Thanks for the great file.


I haven't installed magnets on my subway car. I have, however, installed magnets on another train I printed ( see http://www.thingiverse.com/make:102353 ). These were disc-shaped magnets, similar in style to a fridge magnet, that I had around the house - I believe they were purchased at a craft store - perhaps Michael's. As they are a fridge-style magnet, it has alternating poles, so it doesn't have the neat attract/repel qualities that the magnets in Brio trains have, but it did work. I used a hot glue gun to stick them on, which worked for a while - they have since fallen off. It would be worth looking into a more suitable adhesive (Krazy Glue, epoxy?).

I haven't used these, but you may also want to look at some of these products:




Although I used OpenSCAD for this file, I've recently been playing with "Autodesk 123D" - it is another tool that may be worth checking out.

I printed the pictured model with supports.

I am not building models of other subway cars, but have included the OpenSCAD source files for anyone who would like to use them as a starting point.

Alright thanks for that! Do you think you can make a NYC Subway Car?

Did you print this with support?
