Tom (forum member Krieglok) modified a GGD HW combine into the AFT tool car for me. Tom covered the windows, got the correct decals, and fixed some broken parts on the used car I got from Trainz for a perfect "Tool Car". His work is great and I am now missing only one car, #200 the Power/Bunk car, and the wagons for the flat cars.
The actual Tool Car was originally an 80' HW baggage/dorm.
