Well, January 18, 1978 was an interesting day! The area was digging out from a 12" snowfall.
The salt train was delayed departing the yard. The union and management had been feuding about cabooses not being fit and properly serviced, and there was a problem with the one assigned to that job. Before that was resolved, who should show up but the Federal Railroad Administration inspector in the Motive Power and Equipment discipline. Now one of those guys looking over a freight car is sort of like a State Trooper looking over your car - if they look hard enough they can find SOME defect on almost anything. So the inspector crippled about 40 cars, most of them empty salt cars in the train about to leave.
So instead of that train being gone, leaving room in the yard for the yard crew to switch into, instead those cripples had to be switched out, the remaining cars re-assembled, a new air brake test performed.....
They had been running a set of snowplows on the main line - usual procedure was a double-track plow facing in each direction, with 2 locomotives in between. The plows stopped at the yard a while while the crews went to eat. A single-track plow which had been used to plow the former LV Lima Branch the previous day was tied up at Exchange Street, where it stayed a couple more days account ice on the tracks and unable to get it to Scottsville Road.
An eastbound picked up 55 cars for Dewitt, leaving a little more room in Rochester Yard. And in Buffalo, there was a main line derailment at CP49A, which obviously created headaches for them and ultimately impacted Rochester to a lesser degree.
And while I did not make a post about it, on the previous day, the CTA job on the west Hojack had run out of fuel at Manitou Road.
