GER Class 127
Encyclopedia
The GER Class 127 was a class of a solitary experimental 0-6-0
compound
steam locomotive
built by the Great Eastern Railway
at its Stratford Works
in 1888. It was rebuilt as a simple locomotive in 1895, and withdrawn in 1913.
It was designed using the two-cylinder Worsdell/Von Borries
compound
system, and therefore its initial design may have been by Thomas William Worsdell
, before he left the Great Eastern Railway for the Locomotive Superintendency of the North Eastern Railway in 1885.
The locomotive had a 18 inches (457 mm) diameter high-pressure cylinder, and a 26 inches (660 mm) diameter low-pressure cylinder; both had a 24 inches (610 mm) stroke. This arrangement was the same as that used on the Class G16 passenger 4-4-0 locomotives.
It was reboilered and renumbered 935 in 1890,, and rebuilt as a simple-expansion locomotive in 1895, whereupon it was considered part of the Class N31
, and was withdrawn in 1913.
0-6-0
Under the Whyte notation for the classification of steam locomotives, 0-6-0 represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles, and no trailing wheels...

Compound locomotive
A compound engine unit is a type of steam engine where steam is expanded in two or more stages.A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger...

Steam locomotive
A steam locomotive is a railway locomotive that produces its power through a steam engine. These locomotives are fueled by burning some combustible material, usually coal, wood or oil, to produce steam in a boiler, which drives the steam engine...

History
The locomotive, numbered 127, emerged from Stratford Works in 1888, having been built to a 'Departmental and Personal' account (DP203) rather than the normal 'letter' account, indicating its experimental status.It was designed using the two-cylinder Worsdell/Von Borries
