|The only giveaways in this set of power sitting at the Binghamton engine house are the patch paint on 6509, and the yellowjacket scheme on 6370. Otherwise it could be Idaho. We see both F45s in this photo. I only saw them once working back to back in freight service. BN 6640, to become NYSW 3638, turned into something of a hangar queen, and was beset by a variety of ills that kept it off the road a lot of the time. The trailing unit, 6370, became 3636, and was a steady presence on NYSW trains into the 21st century.
