I don't know if this is the right place for this topic but I'll ask anyways. Knowing that Locomotive's and Rail cars with Friction Bearing trucks can't be interchanged dose this rule also apply to Government Owned Locomotives that operated by the Army, Air Force, Navy, and Marie Corps? If any of these branches of the armed services needed or was transferring one of there Locomotives from one base to another lets say from Norfolk, VA to San Diego, CA dose a road like CSX and who ever the other railroad its swapped with have to take it as well?
From what I have seen, most of the current military locomotives are smaller ones, that could be put on a flat car pretty easily. I do admit I am not too current on just what they have out there, but from what I have seen its a few GPs (which likely have roller bearings) and a bunch of 80 tonners and smaller.
Hope this helps
