Sam is a giant American tender engine originating from the Virginian Railway.


Sodor Story Collection

Sam is a super-sized and super-strong locomotive. He came to the Island of Sodor to help Thomas and Percy with the construction of the Sodor Museum. He collected the heavy loads of rails and stone for the museum. He helped Percy and the bell for the museum back on the rails when Percy fell into a ditch. Afterwards, Sam pulled the bell up to the clock tower when Rocky could not. As a reward for his help, Sir Topham Hatt allowed Sam to lead the first group of people into the museum.

Sam and Logan later returned to the Mainland after their jobs on Sodor were completed.

Thomas & Friends

In Big World! Big Adventures!, Sam is seen pulling a goods train through the Southwest of the United States. He passes Thomas, Ace and Nia who are delivering coffee to San Franciso, and they all greet each other.


Hailing form the United States of America, Sam is the largest, strongest steam engine to ever visit the Island of Sodor. With a big heart to match his massive size, Sam is super-strong and will travel far and wide to help an engine in need.

Technical Details


Sam is based on the Virginian Railway Class AG, also known as the "Blue Ridge". He shares his number with a member of his class. The engine bearing this number was scrapped in 1960.


Sam is painted Persian green and black with white lining. The number "906" is painted on the sides of his cab, his name is painted on the sides of his boiler, near his cab, and "VIRGINIAN" is painted on the sides of his tender, all in white.
