Editing GWR 2900 Class (section)

===Ladies===
A second series of ten similar locomotives appeared in May 1906 (Swindon Lot 164), numbered 2901–10 and named after historical, mythological or poetical 'Ladies'. Nos. 2904–6 had short tapered boilers and short [[smokebox]]es, whereas Nos. 2902–03 and 2907–10 had longer versions. All except 2901 had {{convert|18.125|x|30|in|mm|0|abbr=on|lk=on}} cylinders, giving a tractive effort of {{convert|23382|lbf|kN|2|abbr=on}}. No. 2901 ''Lady Superior'' was the first British locomotive to be built with a modern [[Wilhelm Schmidt (engineer)|Schmidt]] [[superheater]].<ref name="RCTS2"/> The remainder of the locomotives were fitted with Swindon No.3 superheaters between 1909 and 1911 and were withdrawn between 1933 and 1952.

In May 1906 [[Charles Collett]], then assistant manager of Swindon Works, supervised a demonstration run of number 2903 ''Lady of Lyons'', newly released from the erecting shop. By mile-post timings observed from the engine and from passing times recorded at [[Little Somerford railway station|Little Somerford]] and [[Hullavington railway station|Hullavington]] signal boxes, {{frac|4|1|2}} miles apart and with a descending gradient of 1 in 300 between them, a speed of approximately {{convert|120|mph}} was recorded, but this is not reliable enough to be considered a record.<ref>{{cite journal |title=Two Miles a Minute |journal=[[The Railway Magazine]] |date=April 1932 |page=305}}</ref><ref>{{cite web |title=This month in history |url=https://sr-rs.facebook.com/DidcotRailwayCentre/photos/this-month-in-history-may-1906-120-mph-with-a-saintmay-is-a-month-when-we-celebr/1775304622496418/  |archive-url=https://ghostarchive.org/iarchive/facebook/161421647218065/1775304622496418 |archive-date=2022-02-26 |url-access=limited|publisher=[[Didcot Railway Centre]] |access-date=2 September 2018 |date=12 May 2017}}{{cbignore}}</ref><ref>{{cite journal |title=Retirement of G.W.R.
