Advance Registration Required. Tickets on-sale June 3 — 21

For the first time ever, puppies and dogs may ride the rails at the B&O Railroad Museum! Tails on the Rails offers pet owners and their beloved four-legged children an afternoon of historic exploration, a round-trip train ride to Baltimore's Carroll Park, interactive activities, and a "Yappy Hour" at the birthplace of American railroading. All aboard for a howling good time as we help support the Maryland SPCA. Advance registration required. Tickets on sale June 3 —21. One pet per person required.
