Why don't they just standardize like SP did with their "IER" commute train operation in the Eastbay... 22-feet !! Period !! Allowed them to run passenger or freight all they wanted to..
And speaking of Key System, my good Zarkoff, I don't believe your statement about the 19 foot thing. Raised it from 19 ft to what ?? 19-feet was already taller than the 4449 so what's the point ??
Also, how LOW can you go ??? Most everyone on here doesn't realize that the wire thru the KEY SUBWAY was only between 15 and 16 feet MAX.. And according to James Harrison,
SN freight locomotives operated thru here to get to the Army Base, besides SN interurbans, although no one has ever shown me photos of SN locos thru that Subway.
So please explain further, kind Sir !!
