On the sign:
TRANSPORT TRUST
CAMDEN ROUNDHOUSE A rare early railway engine shed, operated 1847-1855 and made obsolete as locomotives outgrew its turntable
The board is on a shed that was used to handle the steam engines of the trains. The round structure is designed to store the “Railway turntable” mechanism, a mechanism that reverses the direction of movement of the locomotive. The building was erected in 1846, but served its original purpose for only about ten years. The place was later used as a warehouse and more. In 1964 the building was reopened as a concert hall where a number of important performances took place including a performance by Jim Morrison and The Doors in 1968.
The sign is one of a series of "Red Wheel" signs marked by the British National Transport Trust.
