The [[North Eastern Railway (UK)|North Eastern Railway]] '''Class T3''', classified as '''Class Q7''' by the [[London and North Eastern Railway|LNER]], is a class of {{whyte|0-8-0}} [[steam locomotive]] designed for heavy freight. Five were built by the NER in 1919 and a further 10 by the [[London and North Eastern Railway]] (LNER) in 1924.<ref>{{Cite book |last=Wragg |first=David |url=https://books.google.com/books?id=A0YwDwAAQBAJ |title=The LNER Handbook: The London and North Eastern Railway 1923-47 |date=2017-07-03 |publisher=The History Press |isbn=978-0-7509-8482-9 |language=en}}</ref><br />
<br />
==Performance==<br />
The first of the T3s, No.901 was outshopped from [[Darlington Works]] in November 1919. A month later the NER organised a test train, over the [[Newcastle upon Tyne|Newcastle]] to [[Carlisle railway station|Carlisle]] line, including a [[brake van]] and the company's [[dynamometer car]] to record the locomotive's performance. No.901 had {{convert|1,402|LT|t ST}} in tow but handled the load with ease, registering both high power and steady acceleration. There were no problems starting on a 1 in 298 (0.335 [[Percent sign|%]]) grade and on the return, with a reduced load of {{convert|787|LT|t ST}}, the engine was untroubled by gradients as severe as 1 in 107 (0.93%).<br />
<br />
==LNER==<br />
Despite their prowess, the original quintet of T3s was not augmented by the North Eastern Railway, a move that would have pleased footplate crews who disliked having to [[Lubrication|lubricate]] and maintain the centre cylinder and valve gear. Instead the enlargement of the class came under LNER. it authorised the construction of ten additional T3s and these emerged from Darlington Works during 1924.<br />
<br />
Of the new engines two were allocated to [[York]] and a further four went to [[Kingston upon Hull|Hull]]. The remaining four gravitated to their natural habitat, [[Tyne Dock]] depot near [[South Shields]]. It was there eventually that all 15 T3s/Q7s congregated. Here they performed the role they were designed for. This was to haul {{convert|700|LT|t ST|adj=on}} rakes of [[iron ore]] [[Hopper car|hoppers]] to the [[steelworks]] at [[Consett]] {{convert|1000|ft|m|0|abbr=on}} above [[sea level]]. On the steepest section, as severe as 1 in 35 (2.86%) in places, one 0-8-0 pulled while another [[Bank engine|pushed]].<br />
<br />
==British Railways==<br />
All 15 passed into [[British Railways]] ownership in 1948 and they were numbered '''63460-63474'''. They remained master of their task till the arrival of [[BR Standard Class 9F]] {{whyte|2-10-0}}s in the 1950s. With the loss of their bread and butter work British Railways retired all 15 of the Q7s in November and December 1962.<br />
<br />
==Preservation==<br />
One, NER 901 (BR 63460) has survived and is currently on display at [[Darlington Railway Centre and Museum]]. It is the newest exhibit at the museum.<br />
<br />
