A strange contraption changes everything

On August 28, 1830, Peter Cooper's Tom Thumb became the first steam locomotive to move a train in the United States, traveling 13 miles from Baltimore to Ellicott Mills in just over an hour.

“On a late-August day in 1830, a strange contraption that looked like a large black bottle atop a small wheeled platform belched white steam.”

Horses gave way to steam

Before Tom Thumb, the Baltimore and Ohio Railroad used horses to pull cars along 13 miles of track. Steam power started replacing horsepower first in Europe, then around the world.

Peter Cooper's bold demonstration

Inventor Peter Cooper designed and built Tom Thumb to prove to B&O executives that an American-made steam locomotive could handle the railroad's winding track from Baltimore to the Patapsco River.

Impressive speed amazed passengers

Tom Thumb traveled at 10 to 14 miles per hour, which passengers found groundbreaking. The locomotive completed its 13-mile inaugural journey in roughly 1 hour and 12 minutes.

“Tom Thumb "traveled at an impressive speed of 10 to 14 miles per hour," amazing its passengers.”

Too small for regular service

Passengers rode Tom Thumb only until March 1831. The locomotive was too small to haul larger trains with more passengers and cargo, so it was scrapped for parts in 1834.

First replica built for 1893 World's Fair

About 60 years after Tom Thumb was scrapped, B&O assistant passenger agent Joseph Pangborn designed a wooden replica for the 1893 Chicago World's Fair to showcase the railroad's pioneering role.

Replica travels the historic route

Pangborn's wooden replica was stored at the National Museum of Railroad History for two decades before being loaned to the B&O Ellicott City Station Museum, the oldest surviving railroad station in the U.S.

Two replicas mark the historic route

The wooden replica in Ellicott City and an operational replica built for the 1927 Fair of the Iron Horse in Baltimore form bookends of Tom Thumb's original 13-mile route from 1830.

“The replicas on display in Ellicott City and Baltimore "form the two bookends of the Tom Thumb's historic 13-mile route that began service in 1830."”

Tom Thumb honored on postage stamp

In 1952, during the B&O Railroad's 125th anniversary, the U.S. issued a 3-cent stamp featuring Tom Thumb alongside a horse-drawn car and modern diesel locomotive, recognizing its historic significance.

Museum welcomes visitors year-round

The B&O Ellicott City Station Museum is open Wednesday through Sunday with free admission. Visitors can see the replica and restored station rooms including the superintendent's office and ticket office.
