Ann is a 100HP 4-wheeled VBGT Sentinel steam locomotive.

It was built in 1927 in Shrewsbury by Sentinel, famous for its steam-powered road wagons.

The loco was delivered to British Tar Products Limited in Cadishead, Lancashire, in 1927 and put into work, shunting Tar wagons around the site day in and day out until its retirement in 1969. The loco is believed to be named after the managing director’s daughter.

The loco was then saved for preservation and moved to the Embsay and Bolton Abbey railway, where it was stored for several years until a local school teacher took on the task of rebuilding the loco with his pupils at Airville School in Skipton.

Unfortunately, funding was short, and the project stalled before the boiler could be overhauled, and the loco was returned to Embsay. In 1995, a Embsay and Bolton Abbey railway member took an interest in the loco and set about finishing the long overhaul. This was completed in 1998, and the loco was then used mainly as a steam heating boiler for the winter months.

After the loco came out of traffic in 2005 and laid outside at Bolton abbey until two individuals bought it in July 2020, the loco then moved back to Lancashire to be overhauled at the East Lancs Railway, where one of the owners worked as a locomotive engineer. The overhaul was rapid, and the loco steamed once again on the 27th of February, 2021

Since then, it has been seen running shunting demonstrations, brake van rides and occasional passenger trains at the East Lancashire Railway. In December 2024, the loco returned to Yorkshire and became a new permanent resident at the KWVR (where both the owners are heavily involved as volunteers). It is hoped that Ann can provide some added excitement at steam galas and special events, running short rides and occasional trains up the Worth Valley.
