Yes true - A few years ago I was lucky enough to have a guided tour of the Severn tunnel and pumping house and control centre care of a friend who worked for Rail Track. The pumps are all electric (of course) and automated and that time were monitored by the guys in the control centre. I cannot fully remember but I think there are seven pumps at work, and if they all fail the tunnel floods in 6 or 7 minutes. I was commuting daily through the tunnel at that time so it was quite thought provoking. Part of the tour involved visiting the culvert below the track bed. Not a place for claustrophobics. It is an amazing feat of engineering, and just wish I could have witnessed the Cornish beam engines at work keeping the tunnel dry. 1 Link to post Share on other sites More sharing options...
