Get ready for a historic holiday treat this December!

This December, take a step inside the B&O No. 4500 “Mikado,” a locomotive steeped in both historical significance and festive cheer.

Shortly after the nationalization of railroads during World War I, the No. 4500 “Mikado” emerged as a pioneer. It was the inaugural locomotive crafted according to the stringent standards set by the United States Railroad Administration (USRA), setting a benchmark for excellence in locomotive construction.

But that’s not all — the Mikado doesn’t just shine with historical importance. During the holiday season, it undergoes a magical transformation, becoming the beloved Polar Express! Decked out in festive decorations and brimming with seasonal cheer, the Mikado comes alive to whisk passengers away on a magical journey to the North Pole.

Join us this December to climb aboard the B&O No. 4500 “Mikado”!


Tours will be available between 10 AM – 4 PM.

Please note: This tour requires participants to climb stairs and walk on uneven pathways. A virtual tour will be available on-site via QR code. Docent Tour Guides stationed near the locomotive can answer any additional questions about the history and physical description of the locomotive. Small children must be accompanied by an adult guardian at all times.


Included with Museum Admission. FREE for B&O Members.
