Fire Queen is an early steam locomotive built by A. Horlock and Co in 1848 for the Padarn Railway.

Fire Queen was one of two identical locomotives built for the Padarn Railway, which connected the Dinorwic Quarry near Llanberis in north Wales with the port at Y Felinheli.

[1] The two locomotives, Fire Queen and Jenny Lind, were built by marine engineers A. Horlock and Co.

[2] Jenny Lind was scrapped, but Fire Queen was placed in a small shed at the quarry workshop, Gilfach Ddu.

It stayed there until the quarry closed in 1969 at which time it was sold to John Smith MP and loaned to the nearby Penrhyn Castle Railway Museum.
