The F designates the front of the locomotive and is required under the Code of Federal Regulations (Title 49, Part 229.11).

OK, I figured that was what it was. Just was'nt sure but decided most engineers needed directions to the bathroom so they put an F there. LOL Thanks


Some people who laugh about the "F" don't realize some locomotives have no cab, some have two cabs, and some have a center cab.

"The front air hose is leaking"

"Which front?"

It could get confusing. Saw a BNSF in Colorado with 12 units on the front and 2 on the rear. I can see the conductor running down the line with a hand cupped over his ear. I had seen it a lot of times but didn'nt know. On the DC 10 airplane the station numbers start at 0 which can be a long way forward of the nose of the aircaft. That way when and if they added to the length it would still be aft of 0, forward of it is -inches and left and right of the centerline are + and - so you can find things according tot he drawings.
