Re: Gramps Tank Cars - trucks

The cast trucks used under the Gramps frameless cars have a 4 1/4" X 7" journal.
The cast trucks used under the 6500 class flat cars have a 5" X 9" journal.
The Andrews trucks used under the 5900 stock cars got used under the 6600 class flats built from SG box and stock cars in the mid 50's.
The Andrews trucks also used 4 1/4" X 7" journals and from a distance look the same as the cast trucks. The Andrews have bolt on journal boxes with a cast side frame as opposed to the one piece cast journal boxes/side frame of the other truck. The Andrews also have a small strap from the side frame under the journal box.
To further confuse this, ASF (who cast the trucks) referred to the one piece cast trucks as "One Piece Cast Andrews" I guess to differentiate them from C&S style bettendorf trucks.
