DHR 778 (originally number 19) is a narrow-gauge steam locomotive, that was built in 1889 for the Darjeeling Himalayan Railway.

The class was designed by Sharp, Stewart and Company of Glasgow and built by them, their successors the North British Locomotive Company (NBL), and three each by Baldwin Locomotive Works (BLW, Philadelphia, USA), and the DHR works at Tindharia.

Number 778 (originally No.19) was built in 1889 by Sharp Stewart & Co at the Atlas Works in Glasgow.

After many years out of use at the Hesston Steam Museum, it was sold to enthusiast Adrian Shooter in the United Kingdom and restored to working order.

Following the sale, the locomotive and its two matching carriages were relocated by the Trust to the Statfold Barn Railway near Tamworth, Staffordshire.
