Due to a speed restriction over defective track between Hayes & Harlington and London Paddington fewer trains are able to run on some lines towards London Paddington.
Impact: Train services running to and from these stations may be revised. Disruption is expected until 22:00 16/01.
Customer Advice: Heathrow Connect services are running non stop between Hayes & Harlington and Paddington.

Track defect leading to a 20mph speed restriction on the up main.

Now expected not to be rectified until 22:00 Thursday.
Which begs the questions... How many trains will pass over it, albeit at 20mph, until then? Will that cause the defect to worsen? How long a daytime closure would be needed to rectify it sooner - and would that entail closure of one or both adjacent lines? On roads, the wear-n-tear increases as the 5th power of the axle load. (Double the axle load, increase the tarmac damage by 32 times.). I don't know how speed affects that calculation. Are there any track engineers out there that can give the equivalent sums for rail? (and for $64k) Will a train derail between now and Thusday 2200 hrs? |

Simple answer. No. There are plenty of 20mph speed restrictions up and down the country for track defects that never cause a derailment. It’s not a new thing. I’ve driven over track before with a 5mph speed restriction. |

Its probably a cracked cast magnese crossing (again)...... They are OK to travel over at 20mph and a track watchman is usually put in place to keep an eye on it. The delay is usually due to having to get the new crossing (they are no lightweight thing), staff and kit on site to do the change. This could all be guessing though, it might just be that Network Rail ( NR» ) aren't organised enough to correct whatever defect it is, in 24 hours.....   Edit: VickiS - Clarifying Acronym |

It may be that was the worst case being quoted, this is now updated to:
"Disruption is expected until 15:00 17/01"

I thought the excessive padding in the timetables was inserted to take care of TSRs▸ ?

Pushed out again Due to a speed restriction over defective track between Hayes & Harlington and London Paddington trains have to run at reduced speed on some lines towards London Paddington. Train services running to and from these stations may be delayed by up to 10 minutes or running non stop between Hayes & Harlington and London Paddington. Disruption is expected until 23:59 17/01. |

SandTEngineer could right, some of the castings are specials and only a few are held Nationally. The other problem is the cutting, stressing and welding in sub zero rail temperatures, UK▸ rail is stressed for a normal 20 oC the Track Engineer may be reluctant to do this operation with the current tempratures |

5mph ESR▸ due to a broken insulated rail joint. Sounds like they are hoping to replace it this afternoon. |

Greetings from 1C12 at Goring and Streatley Fast lines westbound closed ... everyone on the slow lines Err - sorry - main lines closed ... everyone on the relief Said to be a "broken rail" to us on the train. Presumably the track is strong enough to take the new trains? |
