In 2011, the fastest timetabled start-to-stop run by a UK domestic train service was the [[Hull Trains]] 07.30 [[London King's Cross railway station|King's Cross]] to [[Hull Paragon Interchange|Hull]], which covered the {{convert|125.4|km|abbr=in}} from [[Stevenage railway station|Stevenage]] to [[Grantham railway station|Grantham]] in 42{{nbsp}}minutes at an average speed of {{convert|179.1|km/h|abbr=on}}. This was operated by a [[British Rail Class 180|Class 180]] diesel unit running "under the wires" at the time, and is now operated by [[British Rail Class 802|Class 802 ''Paragon'']] bi-mode units, operating on electric power on this section. This was matched by several [[Leeds railway station|Leeds]] to London [[British Rail Class 91|Class 91]]-operated [[East Coast (train operating company)|East Coast]] trains if their two-minute recovery allowance for this section is excluded from the public timetable.<ref>{{cite journal|last=Taylor|first=Dr Colin|author2=John Heaton |title=World Speed Survey 2011|journal=Railway Gazette International|date=September 2011|volume= 167| issue =  9|pages=61–70}}</ref>
