Greenport Scoot

I noticed as it went past the club it had the usual DE in front, Two Cars, and another DE in push mode? Any reason for this? This is the first time I have ever seen that before.

I guess it was a cab car failure. The 417 was brought in on Thursday by MP15AC 168 . Hopefully they'll keep that setup next week. I was only able to get a shot at Holbrook westbound at 4 P.M.
