NJ Tranist Arrow III Trucks

I'm sure this has probably been answered before. I did a quick search, but did not find the specs. I'm building HO scale Arrow III trainsets and need to know the wheelbase of the trucks. I believe the wheels are 33". Any help is appreciated.

They are GSI 70s, a standard type.

All I know is they are an inside bearing truck. Probably the same trucks used on the Comet coaches made by Pullman Standard and Bombardier. Also the Metro North Bombardier are probably the same and Amtrak's Amulets have them as well. Dont know who would have those trucks other than Walthers who had the Bombardier Coaches in NJT and maybe others. Sorry I cant be of more help.

Comets are GSI 70s.

The trucks that the Arrow IIIs uses are the same as one on Silverliner IV

Then are we talking 9 ft wheelbase from center axle to center axle on the truck? Thanks.

I thought I had seen some time ago that the truck wheelbase was 9 ft. I guess I could go up to Hoboken with a tape measure.....

Stanton NWSL has a large selection of powered drives for model railroaders.
