There were 23 DE's, 23 DM's. One DM was downgraded to a DE, another I believe burnt badly. This one, 511 damaged. SO it sounds like we still have 24 dE's, maybe 20 DM's?
In the meantime, LIRR added all sorts of east end DM service. And on summer weekends there is a severe shortage of everything diesel - DM's, C3's, etc. And the worse it gets, the more trains get badly shortened or cancelled. In the meantime, as I noted, the PJ line's last direct from Penn to Port Jeff departs 4:49 - before rush hour. That line needs another direct train around 6PM from Penn to PJ, possibly replacing the 6:01 that's horribly slow and a long wait at Hicksville each day. In the meantime, Oyster Bay is said to need better service. And it will likely be many years before LIRR finally gets - in usable condition, new DM's of some sort along with new DD cars.
