Some of the cars returned back as Tim says - another handful are being tested now this week for future use with a C3 cab since MARC doesn't want any mods done to their own cabcars. Rightfully so
A test train was seen this morning at 10:50 AM between Woodside and Forest Hills in Queens with C3 #5020 leading, MARC cars, 7754 7714 and 7707 with trailing power #413. This was headed westbound towards Long Island City.
If MARC cab cars are not to be used as such by LIRR why did almost half the leased fleet consist of cab cars? Don't you lose a few seats with the cab configuration? Or was this a situation of having to take whatever was available at the time? 3 out of 8 seems like a high ratio of cab cars in any case.
