Thank you! I just wasn't sure.
Check out the Balfour and Colucci Creek Southern Railroad, my proto-freelanced N scale model railroad, at bccsrailroad.weebly.com or on Youtube on my channel, N Scale Train Boy.

If you are talking about the 'F' on the frame at the front of the locomotive, it means that this is the front of the locomotive. All major railroads should have this as it is a FRA requirement.

Does anybody know why Union Pacific SD90/43MACs have "f"s on the front of the locomotive's sides at the bottom?
