Nastiest sounding horn ever made sitting up top waiting to deafen hundreds of engineers, B-0-Ts, and assorted train crew. LAMCO drilled a hole in the roof and put a porthole up there for ventilation when they cut cabooses off. All it did was make sure you heard the horn better before you got deaf.
Nice touch on the number font on the side of the cab, though. Straight off the Green Team. I reckon those are 'visible' GP40 (or GP35?) maintenance demonstrators? Is Snippy the only one here who built a "Visible V8" as a young cherub? Snippy was more intu huffing glue than being a great model builder.

Display was sometime 1969 or after in Cumberland, apparently young Clavalin didn't see it, tu far away from Cumberland back in those days and a lack of mobility.
It came up on the B&O Historical discussion group, it just says display at Cumberland after April, 1969, I just found it sort of interesting that they'd display a locomotive to the public with the hood removed. That's all I know, I wasn't trying to create a mystery.
