Rolls Royce took over the Sentinel Works in Shrewsbury in 1957 to use it for
production of its range of diesel engines. Sentinel had produced steam lorries and
small steam shunting locos for over 30 years, so RR decided to use their expertise
to produce a diesel shunting loco using their own engines. Instead of a simple
conversion of the previous steam shunter to diesel, the design team took a
completely fresh view of the requirements of the industrial loco and came up with
an award winning and stylish design. 290 Sentinels were produced from 1959 to
1971 to four sizes, all utilising standard cabs and bodywork, the largest being the
twin-engined 0-8-0. The final development was the shaft-drive "Steelman" 450 hp
0-6-0.

DH16 is a class LB 0-4-0CD (Chain Drive) type of which 104 were built. It is
one of 18 supplied to the Manchester Ship Canal Railway from 1964-66. It
worked there until the closure of the docks in 1970 and was sold to Bowaters at
Ellesmere Port, where it worked until 1980, when it was donated to the fledgling
East Lancs Railway. The ELR used it extensively on the reconstruction of their
line, but in later years it became disused and abandoned in a very sorry state. It
was rescued by DEPG member and Sentinel enthusiast Colin Girle, who took it to
Foster Yeoman's Quarry rail shed at Merehead in Somerset to restore it. By
August 2001 most of the work was complete and the loco moved to Williton for
repairs to an axle journal and drive chain, before taking up its role as Williton
depot pilot. The loco is finished in it's original livery of Oxford Blue, lined out in
yellow.
