rtraincollector posted:NS leases/buys other railroad used engines. I saw the other day a UP & CN running MU on NS track. No NS engine in the set. Just those two running MU. So that's my guess. I see UP engines running here quite often, but usually has a NS MU with it.
The 4513's been in service on the NJT for several years, so it's not a new delivery.
NS would have to be really hard up to lease a locomotive designed specifically for commuter service and press it into freight service. I would agree with Jim, it's most likely going to/from Bombardier for work.
