1000th HST power car failure since Dec 06 time began - this week! - 1105/3144 Written by David Preston on Wednesday, 17th January 2007 I've heard that FGW has experienced it's 1000th High Speed Train (HST) power car failure this week, in only a month or so of running the new timetable. It would appear that FGW just aren't maintaining the FGW fleet to the same standards. If they do drop to a low point, we might have another 'Maidenhead fire' accident in 1995 in which a power car caught fire, and engulfed a few coaches. In the rush to leave the scene, a passenger died after being hit by another train. Last week I was returning from Paddington and came to a halt near Dauntsey bank on an HST because a new MTU powered HST train suddenly gave up the ghost. I wouldn't be surprised if FGW have another accident due to their disregard for maintenance.

Re: 1000th HST power car failure since Dec 06 time began - this week! - 1105/3159 Written by Steve35 on Wednesday, 17th January 2007 What do you mean by a failure though? It certainly isn't a failure in the sense of a train breaking down and grinding to a halt. Reality check: 1000 'failures' in 1 month (say 31 days) is 32 per day. Which would mean for example every train from Bristol Temple Meads to Paddington 'failing' every day.... Hmmm. Re: 1000th HST power car failure since Dec 06 time began - this week! - 1105/3161 Written by Nick Field on Wednesday, 17th January 2007 Would I be right in thinking that many things recorded as a 'failure' not just on HST's but all trains very often mean that the train can carry on to its destination or can run all day until it get a chance to get to the depot for the fitters to look at it?

[/quote] I think David meant the 1000th train failure since First Great Western came into existance , which was quite some time before the new franchise / timetable took effect.

Re: 1000th HST power car failure since Dec 06 time began - this week! - 1105/3171 Written by David Preston on Wednesday, 17th January 2007 I just heard this from a reliable source, someone who is working on HST2 or the intercity Express project as it is now known. A failure could take many forms, just I heard they had a 1000 failures which seems a lot to me. Here are some definitions of a failure! I should know as I work in railway safety. Equipment Reliability [color=Red]The probability that, when operating under stated environmental conditions, process equipment will perform its intended function adequately for a specified exposure period[/color]. Failure Frequency [color=Red]The rate of occurrence of an event per calendar time or per distance travelled, as applicable.[/color] Failure Mode [color=Red]A symptom, condition, or fashion in which hardware fails. A mode might be identified as a loss of function; premature function (function without demand), an out-of-tolerance condition, or a simple physical characteristic such as a leak.[/color] Failure Rate [color=Red]The rate of occurrence of an event per hours in service or per distance travelled, as applicable[/color]. Frequency [color=Red]A rate of occurrence.[/color] link to index of articles |

Save the Train was the campaign to bring an approriate train service back to and through Melksham. Most big contributors are still around writing at the Coffee shop forum where new members are very welcome. The train has been saved - sort of - we have stepped back up from an unusable service to a poorish one but it's doing very well. We did that through setting up the TransWilts Community Rail Partnership. That fulfilled its early objectives; it has been taken over by local and regional government types who are now doing medium and long term work. The team from this forun can also be found at the Melksham Rail User Group (which was the Melksham Rail Development Group at the time these articles were written and we had no users. We mustn't loose sight, though, that the train service remains poor and needs our community support in marketing and campaigning to keep it going in a positive direction ... and all the more so when we're expecting to find a different normallity once we get out of the Coronavirus Pandemic and head for zero carbon via the climate crisis. Yes, it's saved ... it's now a key community facility ... the need for enhancement and the strong and near-universal local support remain, and the rail industry and goverment remain slow to move and provide the enhancements even to level us up with other towns. Please support the Melksham Rail User Group - now very much in partnership rather than protest with the rail industry and local government, including GWR, TransWilts and unitary and town councils. And please use the trains and buses, and cycle and walk when you can. -- Graham Ellis, (webmaster), February 2021 | |||
