The original tank house was demolished circa 1968.
The current structure is a modern replacement that is similar in design to the original, but slightly smaller (e.g. there is just one window in the front wall of the base, rather than two).
A commemorative plaque fixed to the front wall states that the current structure was:
APPLEBY ROUND TABLE
It is a functional structure and it supplies the nearby water crane located at the south end of the 'Up' platform (Location ID 277230). Unlike the original, the modern tank house is not able to supply water to steam locomotives using the 'Down' line and road tankers parked on the station forecourt are currently used for this purpose.
