Decoding the Truck Classes

[NW Mailing List]

 This is only a partial answer: the truck class numbers were N&W specific. Just like equipment class numbers.

I have a copy of the 1975 N&W General Manager Motive Power and Equipment List reprinted by the Society some years ago. In the equipment lists, truck classes are provided. But no descriptions or decoders are included for the truck class numbers. Is there a cross reference that describes builder and type for a given class number? And are these codes N&W specific or are they an AAR code?

Specifically, I have ordered a B-121 boxcar kit from Cannon & Co. I have to supply a pair of trucks. The equipment list specifies that the B-121’s had T175 class trucks (with 6”x11” roller bearing journals). But to be as accurate as possible I would like to find what the T175 truck is and then what is the closest HO model available. I would have the same question on some of the other classes, but this is my current puzzle. I searched the archives for T175 and got a hit on the Letter of Approval for the B-121 boxcar. The data may be in there, but I wonder if there is a class list for trucks similar to the equipment list? Or has there been an article written on the subject?

  

Thanks for any knowledge that you can send my way.
