Love the U23-7B (?) with Alco trucks.  That's something we didn't see very often out here in the Southwest.

B23-7. You might have had a chance on the Santa Fe - I think some of theirs might have had the "trade in" trucks from the older U-Boats they traded in to GE for them. Later ones had the "Hi-Ad" trucks.
