Being a Canadian, most of the trains I end up seeing are either Canadian Pacific, or Canadian National... the latter being the main line that runs near my house. I've seen the occasional Norfolk Southern locomotives on the line, but a few days ago, I saw a Union Pacific locomotive (SD70, I think) in a consist with a Canadian National (SD60F). The road number on this Union Pacific was either 5006 or 5008... Can anybody shed any light on this odd lash-up?
