TT scale trains and models

Should the drive shaft between the motor and truck be perpendicular
or parallel for smoothest operation?

The wagon top boxcar looks great; even without the rivets!

Any news on the MTB Union Pacific SW9?

Excellent modeling. Thank you for sharing the video.

I drew up a TT Standards Gauge in CAD using the NMRA standards.
It is based on the HO Style NMRA Standards Gauge.
The pocket for the coupler is for a Micro-Trains 1015 N scale coupler.
DXF file attached.

Kind regards,

I am wondering what would be the correct dimensions for a Micro-Trains 1015 coupler to get it centered to the .281" height. MT-1015-TT-scale.jpg The draft gear box measures about .205" wide x .128" thick. The coupler appears to be centered in the draft gear box. Should I use .345" for the upper dime...

Why is everyone so obsessed with the body shell for a new locomotive, when there is no decent quality drive system to put it on? The TT_IMS group over on Yahoo Groups produced a resin GP38 shell, whatever happened to plans for the drive for that? What is needed first is a good set of trucks with qu...

I have probably reread all 38 pages of this project about 5 times already. I sure would like to see the chassis part of this project finished for an example of how to build one. The knowledge learned then could be applied to other models. Building a chassis seems to be more difficult for most of us;...

Could you please check the location again?
I think it might be in La Crosse, Wisconsin.

Kind regards,

A SD40-2 locomotive measures 68' 10" over the coupler pulling faces.
That makes a TT scale model that is almost 7 inches long.
With a model that long, should the couplers be mounted on the frame-shell or on the trucks?
