They are in Dunkirk Yard, which is south (east) of Lower Holban on the Montauk Branch. The lead extends from the east end of Holban, parallel to Montauk #1 and decends into Dunkirk. The yard is used exclusively for MW operations, and is so named as its entrance for vehichular traffic is on Dunkirk Avenue.
The cars are shot. I believe they were once part of the MW in-house welded rail train which was replaced by outsourcing. If that is not correct, I know for a fact they are used for storage of I-don't-know-what in the yard. They are graffitied and rusting badly.
We called them "Blimp Cars" because of their upper roofline. As a young engineer, I remember deadheading in them back to Jamaica. The windows were so tall that when you sat in a window seat, there was concern that a stone might take you out enroute.
Wheelslip! Back to the Barn.
