Two MRS-1 ALCO's (B2085 and B2090) belong to the Eastern Shore Railroad, in Virginia and are stored at the Little Creek car float terminal in Norfolk. I don't know if they are in use or if they even work but they have been relettered. The ESHR connects Norfolk (via car float across the Chesapeaake Bay to the Eastern Shore of Virginia) with Conrail at Pocomoke City, Maryland. This used to be the DelMArVa Division of the PRR.
