This is the instructions I have made of a AAR 50 ton Freight Truck by L-Gauge at L-Gauge.org
Modified to use ballbearings by Knud Albrechtsen.
Special thanks to the LDraw forum community for making this element for me

Train axles can be bought at E-Bay Here

Update:

The part list can be downloaded here

Instrutions to download and use the partlist can be found here .

As it takes a lot of time for me to make these instructions, please make a donation to my paypal account to insure the further development of instructions on this site.

All instructions are created with LDCad, LPub3D and the LDraw Library of Parts.
