Decoding the Truck Classes

[NW Mailing List]

Searching the NWHS archives for T175 yields this hit:

http://www.nwhs.org/archivesdb/listdocs/select.php?index=search&Searchword=T175;
obtaining a copy of this document "may" indicate the original manufacturer
of the truck.  I have viewed some truck drawings at the archives where
there is a notation to the effect of "traced from Buckeye......", etc.

N&W usually assigned its own class to most equipment; the exception that
readily comes to mind is the diesels; however most other freight, passenger
and steam equipment had N&W specific class designation.

I am not aware of any cross-reference for N&W truck classification with
actual manufacturer; such a cross-reference, however, might be a useful
resource for modelers.
