Wrong kind of pressure

Wrong Kind of Pressure Disrupts Trains By Peter Woodman, Transport Correspondent, PA News Rush-hour rail passengers were treated to a new excuse for broken trains today - the wrong kind of atmospheric pressure. A sharp rise in atmospheric pressure caused havoc with the fine workings of Electrostar 357 trains used on the Essex Coast to London services run by the c2c company. Eight of the trains lost power, causing severe delays to journeys into and out of London's Fenchurch Street station. A c2c spokesman explained: "Oil pressure plays a very important part in the running of the engines on these trains and this pressure is determined by atmospheric pressure. "The atmospheric pressure in the c2c train area this morning was more than twice what it was yesterday and this led to an airlock which, in turn, led to the falling down of the pantograph which collects power from the overhead wires." He went on: "We had been working with our engineers to introduce a modification to avoid this kind of problem, but it has not been installed yet." -- Paul About 30psi or 2bar?

Exactly what I said to the Fleet Manager this morning, it seems he was the "Spokesman" in the news article and told the staff and the media 2 diffrent things -- To reply direct, remove NOSPAM and replace with railwaysonline For Railway Information, News & Photos check out the Award Winning Railways Online at http://www.railways-online.co.uk |

I've had a look at the Met Office data for Shoeburyness for the night in question (Sun/Mon 18/19 April), and the pressure rose from 982mb at 22:00* Sunday to 992mb at 11:00 Monday. The Met Office uses words to describe the change in pressure according to the size of rise or fall over 3 hours. The fastest rises in any 3-hour period were of 3mb (22:00-01:00, 05:00-08:00, 06:00-09:00). There is nothing unusual about that. It would take a rise of double that rate to qualify as a "very rapid" rise in Met Office parlance. * All times BST. -- Richard J. (to e-mail me, swap uk and yon in address) |
