This is one of Frisco s FP-7s the numbering starts at 5040 and runs thru approx. 5051 or so...note the 2 air hoses...one is the train air brake line and the other is the air communication line which was used by conductor or brakeman to signal the engineer...Frisco passenger crews did NOT have radios although this loco had a radio account it s dual service in freight as did the steam generator equipped Gp7s . A little know fact that none of the passenger E units had cab radios....Bob Zucco
