More progress on the SD45 (SCXY and SOU). I got most of the details done on SOU 3130 and 3114. 3114 comes from a slightly different line in the SOU SD45 roster. It will be the only one of the four I'm doing with white number boards and it also has more antenna than the other 3. UPDATE: I got an email explaining that the white numberboards indicated a Locotrol Unit. These engines could control midtrain pushers via radio signals to a mu'd boxcar. Pretty cool stuff for the time period. Thanks for the info Tyler!
