Can anyone shed any light on what happened to the 08.01 @ Chesham this morning please? I had just gone through the barriers and was about to get on the train when the driver announced it was being taken out of service and taxis would be provided to Chalftont. We were then told the "taxis", which never arrived, were now a bus. However, after 30 minutes waiting outside Chesham station and no sign of a bus I had to phone the wife (who thankfully has the day off today) to come and pick me up and take me to Amersham. I heard there was an incident at Great Portland Street but surely that is no reason to kick us off at Chesham as the train would have to go through Chalfont anyway...?

At approx 7.50, the train had overran the usual stopping point at Chesham thus resulting in some damage to the fixed red lights/ buffer area.

Oh dear. Thanks Tecchy. Do you know if this is going to result in delays for the rest of the day?

No prob. The Met has suffered today with lots of incidents so I am unsure to be honest.

Yeah the Met seemed to have a few fast trains today towards Amersham/Chesham at around 2.30ish  |

When I came home at 22.00 all Amersham/Chesham trains were running fast as there was a points failure at Watford South Junction. The Pinner crowd had to suffice with a reduced 4tph service ;D

I dunno, if it was an A they could just hook up a battery loco at the end or just drive it from the other end straight to Northwood sidings, and get someone with a hammer to bash the FRL back into place  |

No damage I'm sure. The red light fixing is designed to give way when struck by a train. |

Weren't FRL's hinged and sprung at one point?

Haha, that positively invites them to be "kissed". When the Pendolinos demolished the pair at Lime St, they seemed to deliberately fail near the base.

At approx 7.50, the train had overran the usual stopping point at Chesham thus resulting in some damage to the fixed red lights/ buffer area. I have noticed that there is no sand drag anymore at Chesham and only an unforgiving concrete buffer stop with S stock overriders. There is nothing to absorb an impact and reduce its severity either by friction or hydraulic means. |

There is nothing to absorb an impact and reduce its severity either by friction or hydraulic means. The speed control trainstops and final fixed trainstop provide the mitigation, so any impact speed would be very low indeed. Short sand drags are not very effective. |

There is the speed control signalling, but there used to be a sand drag there, which is better than just a fixed concrete block alone and there is very little overrun from the stopping position to the concrete block. Everywhere else on LUL where passenger trains enter a terminal platform, I can think of, there is either a sand drag and/or a buffer/arrestor. At other locations we have seen older buffers being replaced by modern ones. If for any reason an S stock should lock up its brakes and slide the trips will not be of much use.
If there is a problem with space, it needs to be made.

Remember it's all on a fairly steep uphill gradient into the station though. Let's let the professionals do their job and trust them |
