Hey wow, I didn't know there was a real BEEP. Thanx for the info, Rusty. One-of-a-kind Santa Fe rebuild, GP7 equipment on a Baldwin frame. Originally #2450, renumbered to 1160 then 1460.
Maybe it should be a "B-BEEP" because of the B-B wheel arrangement, cuz the RMT Beeps are just a two-axle "B" wheel arrangement.

"Official name SWBLW (SWitcher, Baldwin Locomotive Works)" - does that make it a SWIBAL ?
