A munitions depot for the Royal Navy it was in use as a munitions storage facility since the 1940s and had facilities for the underground storage of an extraordinary amount of munitions, including a bunker to hold nuclear warheads.  Surplus to Ministry of Defence requirements, the site was decommissioned in 2003 and put out to tender in November 2005.

After the facility closed, 6652 was briefly on display at the “Explosion” museum in Gosport, from where it was purchased by the L&B in August, 2007 along with a box van, flat wagon and wooden bodied brake van. Built to 2’ 6" gauge all needed regauging before being used on the railway.


The locomotive is fitted with a 60 horse power, 4-cylinder Gardner 4LW diesel engine, connected to a torque convertor driving a single speed Hunslet gear-box, with hydraulic clutches for forward and reverse. The final drive is by sprocket and chain.
