Transport secretary Heidi Alexander marking the first renationalised trainThe first train to be brought back into public ownership under Labour was (metaphorically) derailed today, turning the major moment into a bit of damp squib.South Western Railway (SWR) officially came under public ownership at around 2am on Sunday morning as part of the government’s promise to create “better services”. The first service of the day – normally be the 2.27am train from Guildford to Waterloo – was cancelled.So that meant the pressure was on the 5.36am service from Woking to London Waterloo to mark the historic occasion.But any jubilation from the occasion quickly evaporated when the journey had to rely on a rail replacement bus service between two stops, Surbiton and Clapham Junction.It turns out that bank holiday engineering works had overrun meaning the train was no longer able to go down the intended track.But Keir Starmer seemed to overlook the embarrassment this morning,
