G&SWR 128 Class
Encyclopedia
The Glasgow and South Western Railway
(G&SWR) 128 class is a class of two 4-6-0 steam locomotives designed by James Manson
as a development of his 381 Class 4-6-0s, and were his final locomotive design before he retired. They were built in 1911 by the North British Locomotive Company
at its Queens Park works and were considered both good looking and excellent performers.
Originally numbered 128 and 129, they became 512 and 513 in the G&SWR renumbering of 1919. Under the grouping
they became LMS
numbers 14673 and 14674, but were scrapped in 1933 and 1934 under the LMS drive for standardisation.
The 128 class, along with the 381 class, were the only G&SWR locomotives to use the 4-6-0 wheel arrangement, and were also the only G&SWR locos to have Belpaire fireboxes
. As originally built, No.129 had a Weir feedwater heater
mounted on top of the boiler between the chimney and the dome, but this was removed in 1919. The same locomotive operated for a period as a 4-4-2 after it broke a trailing rod.

Feedwater heater
A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system...
