Locomotion No. 1

The original Locomotion No. 1, photographed in 2009 at the Head of Steam museum in Darlington, England. George Stephenson's 0-4-0 hauled the opening train of the Stockton and Darlington Railway in September 1825, the first steam-powered public passenger train journey in the world, which is why the railway's 2025 bicentenary put it back in the spotlight. In March 2021 it moved to Locomotion in Shildon, near the spot where that journey began, under an agreement that lends it back to Darlington for spells, so check which museum has it before a visit.
