A very strange one. About halfway into the 8 PM Hermosa-Cheyenne run, I passed an oncoming train (one of several)- and after that, the headlights/ditch lights, which up to that point had illuminated the track and trackside signs adequately, suddenly became as useless as those on Clinchfield and I had to finish in the dark. Also, the stop marker at Cheyenne failed to appear. Platform: Steam/Win 10 DLC: Sherman Hill Loco: SD70-ACe Weather: July/clear Service: Hermosa-Cheyenne Yard (Automotive) 19:41
