B&O Unlocked: MARC No. 7100

The CE-15, nicknamed the porcupine, stands as a testament to innovation, marking a pivotal moment in locomotive design with its groundbreaking features.

We’re celebrating this iconic locomotive for its pivotal role in modernizing commuter rail travel.

The SEH No. 4 – known affectionately as the “St. Elizabeth” or “Little Lizzie” — was one of the last steam locomotives ever produced in the United States.

Before the era of private jets, the No. 908 was the pinnacle of luxury travel for business executives, celebrities, and politicians.

This exceptional locomotive isn’t your ordinary steam engine—it’s a unique “fireless” steam locomotive crafted by Heisler Works in Erie, PA.

This self-propelled streamliner revolutionized rail travel as a Rail Diesel Car (RDC) developed by the BUDD Company in 1949.

Named for their bumpy and unstable riding conditions, “bobbers” served as business offices, mobile lookout towers, and sleeping quarters.

From a time when rail passenger services faced fierce competition from airlines and automobiles the BUDD Slumbercoaches were innovative creations designed to counter this threat.

The PM No. 11 stands as a diesel switcher, purpose-built to navigate rail yards and industrial parks across short distances.

The No. 1083 is no ordinary diner — it boasts a streamlined exterior reminiscent of the mid-century, while its interior design harks back to the 1940s.

The “Sweet Toot” was the powerhouse responsible for maneuvering freight cars loaded with liquid and granulated sugar within the confines of the iconic Domino Sugar refinery in Baltimore.

Join us as we unlock the legendary B&O No. 4500 “Mikado,” a locomotive steeped in both historical significance and festive cheer.
