Considering the fact that the B&O discontinuted all passenger service to (and through) Wilmington, DE on April 26, 1958, it was quite a nice catch to see a MARC unit in town as one could argue MARC as the passenger decedent of the B&O. Number 57 was coupled to the front of an Amtrak HHP-8 (One could argue a PRR descendant) due to electrical issues on the Corridor March 19th, 2011. Sharp unit, perhaps a nice substitute for AMTK #156.
