I just got back from a two day trip to Harrisburg PA and here’s all the foreign power I saw.
UP:
SD?? (it was behind an NS GE in Enola so I couldn’t see what it was)
2 SD70Ms (one on the ex RDG bridge, one in Enola)
C40-8 (on RDG bridge)
3 AC4400s (two in Enola, one on RDG bridge)
1 SD90MAC (on Rockville bridge)
CSX
AC4400CW and C40-8 (both on RDG bridge)
CN
4 unknown (in Enola behind a few rows of cars)
Other
FURX SD40-2 (RDG bridge)
SP AC4400CW (Rockville bridge)
plus other rare engines including RC Highhoods, and stores GP38s (including Sprit of Conrail and Philly Division GP38s) and a lone B36-7 (taken off the NS roster a year ago).
The most amazing thing is I found out on a few websites that BNSF, UP, CSX, FURX, NREX, and SP came through also (the UP, CSX, FURX, and SP were different from what I saw). Nice relief from NS GE’s.
