Train 949 today didn't have its usual maxi-bomb equipment today and we had to switch to the upper harlem mini at Southeast. At the northern most vestibule behind the BL-20gh there was a foot plus of snow accumulation, and when I got off the train I saw it all over the control panel... Does accumulation like this cause problems? I've never seen it that bad in a maxi-bomb vestibule.
Yes, during times like these snow accumulation in the vestibules, more importantly the steps are a problem. It's also a pain when the traps are iced.
About 949, the NHV is down a considerable amount of cars for service. Perhaps the RR felt that set was needed for service on the NHV line. I'm only guessing here, but it has been evident the past few days a lot of trains are being substituted for bomb trains that are normally covered by EMUs.
