Once a year, Baltimore's oldest stretch of railroad track belongs to the dogs. On October 25, the National Museum of Railroad History & Innovation will host Tails on the Rails, letting leashed pups and their owners board a train for a one-mile ride to Carroll Park, followed by a costume parade and a Howl-a-Ween party back at the museum.
It is a dramatic exception to how the museum normally operates. Under standard policy, pets are strictly prohibited from the 40-acre campus except for working service dogs, which makes this single October afternoon the only time all year that dogs are welcome on the grounds and train cars at all, according to Spotatrain. For one day, the museum that used to be known as the B&O Railroad Museum turns its rules upside down for the sake of wagging tails and puppy playdates.
As reported by WBAL-TV, the day kicks off with Yappy Hour at 1 p.m., where dogs and their people can mingle before boarding the Mile One Express for the trip to Carroll Park. Kris Hoellen, executive director of the National Museum of Railroad History & Innovation, told the station that the dogs genuinely take to train travel, saying they “sit on their seats and look out the window.”
A Ride Down America's First Commercial Rail Line
The train itself travels a route with serious historical weight. The Mile One Express runs along the first commercial mile of railroad right-of-way ever laid in the United States, where construction began in 1829. The Baltimore & Ohio Railroad had been chartered in 1827 as the nation's first common-carrier railway, per the National Museum of Railroad History & Innovation. Dogs riding those rails this month will be retracing the literal birthplace of American commercial rail travel.
Once the train reaches Carroll Park, the station notes that participants can enjoy a puppy playdate before heading back to the museum. Carroll Park itself carries its own history: it is Baltimore's third-oldest public park, built on land that was originally Mount Clare, a mid-eighteenth-century plantation estate associated with barrister Charles Carroll, according to Explore Baltimore Heritage. The city acquired the park in 1890, and it was later redesigned by the Olmsted Brothers.
The museum campus has a deeper historical layer as well. It is designated as a National Underground Railroad Network to Freedom site, with at least 27 freedom seekers known to have passed through the property while escaping northward, as detailed by Atlas Obscura. Mount Clare Station served as a crucial transit point for those fleeing enslavement prior to the Civil War.
Costumes, Vendors and a Celebrity Judge
Once the train returns from Carroll Park, the party shifts into its Howl-a-Ween phase, with WBAL-TV reporting that Misty Brewery will be on hand alongside vendors selling dog-related items and treats. The centerpiece is a dog costume parade, judged this year by celebrity judge Dalencia Jenkins, who will attend with her own dog, Skyler, per the station's report.
The event has grown more elaborate in recent years. During the October 2025 edition, the museum introduced a designated Doodle Car on the Mile One Express and ran social media voting to let fans choose additional breed-reserved railcars, according to the National Museum of Railroad History & Innovation. It is a level of canine-focused programming that stands in sharp contrast to how most rail operators handle pets.
Commercial intercity provider Amtrak, for comparison, restricts onboard pets to small cats and dogs weighing 20 pounds or less, and only inside enclosed carriers stowed under seats for a fee, according to Amtrak's own policy.
Tickets Fund Two Shelters Amid Rising Strain
Admission costs $20, and WBAL-TV reports that proceeds will be split between the Baltimore Animal Rescue and Care Shelter and the Maryland SPCA. Dogs must stay on a leash throughout the event, owners are required to bring their own waste bags, and everyone must pre-register and provide proof of rabies vaccination ahead of time, per the station.
The fundraising beneficiaries carry significant weight in Baltimore's animal welfare system. BARCS has served Baltimore City since 2005 and provides care for 10,000 shelter animals annually. The Maryland SPCA, founded in 1869, adopts out roughly 2,400 animals each year, per an ArcGIS account of the organization.
A Museum Rebranding for Its Bicentennial
Tails on the Rails also arrives amid a broader transformation at the host venue. In July 2026, the institution formerly known as the B&O Railroad Museum officially rebranded as the National Museum of Railroad History & Innovation as it looks toward the 2027 bicentennial of American railroading. The new name gives the museum an expanded national profile just as it opens its gates, however briefly, to Baltimore's dogs.
