On my way to USAF Survival School we took a few days for some railfanning. The railfanning was fun, the school, well, not so much. This unit is actually BCR but bears the old paint scheme.

None of the units had an "F" on either end (Some wierd Canadian thing?) but his end has a pilot, marker lights and a bell. That says "front" to me. Very likely the only RS-10 I ever saw.
