This is the first SL-SF GE "U Boat" or any "U Boat" for that matter, I have attempted. I see there are a few discrepancies in the Bowser model. I did add a few Rasza, wheel slip modulators a speed recorder, A 5 chime Leslie horn, a couple DW 130's pilot plows as well as a bunch of weathering chalk, some Dull Coat. I would welcome some input from my Frisco Hoghead friends, I am familiar with the newer GE's, but would like for someone that ran these, tell us how these old GE's loaded and ran. I have been told they were FRA bait for oil leaks especially on the walkways and were not dependable. Again, I would like to learn more about them.
