but they need to explain too why our rails have problems at temperatures other countries don't!

Not at all impressive is it?!
Though the section of track affected is only 40mph anyway (with a small bit at 50mph) so with a few services thinned out most others are only suffering minimal delays.

Very poor.
I can understand the need for speed restrictions in exceptionally hot conditions, but to need such restrictions during a moderately warm early summer day is a bit worrying.
What will happen if we get a hot summer ?

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU▸ is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

Phew! A scorching 20 degrees (68 Fahrenheit in old money), God help us if it gets over 80. |

There is also a process called CRT‡ (Critical Rail Temperature) which can applied in warm weather where civil engineering works disturbs the track formation, shoulder ballast, new UTX (Under Track Crossings) etc. There is quite a lot of civils activity in the Ladbrook Grove area.
There is also a cannoning effect caused by the buildings and direction of the sun the area can heat up very quickly with very little wind cooling. We used to regularly get HV cable joints fail in that area in the summer due to the heating of the sun caused the cables to expand and move.

............here we go folks! At least it's a lovely sunny day to stand on a platform waiting for a train which may or may not arrive (eventually!) Looks like West Drayton/Hayes/Southall area again  Cancellations to services between Slough and London Paddington Due to signalling problems between Slough and London Paddington some lines are blocked. Impact: Train services running to and from these stations may be cancelled, delayed by up to 30 mins or revised. Disruption is expected until 18:00 18/06. |

I must have just missed this - I caught the 13:18 Paddington to bedwyn and had no problems with the journey at all |

Looking at the departure boards it looks as if the disruption is not too bad at the moment. 16:00

I actually think the FGW▸ staff and the NR» staff are managing these disruptions quite well over the last few weeks.
The Padd dispatch team on 13 & 14 are turning the trains around as quick as they can whilst still letting passengers get there from the main concourse when there is a late announcement.

Numerous cancellations and short workings for most of today, many of the earlier problems due to overhead wire problems, together a few signalling failures and train faults. Most of the later evening issues caused by a fatality  |

I found this announcement by fgw particularly perplexing:
MAI▸ to PAD» on your route: 07:17 will have 3 not 5 coaches - an unusually large passenger flow.
How does increased demand lead to a reduction in carriages?

Increased passenger flow elsewhere maybe?  |

Why would "overhead wire problems" lead to short formations on FGW▸ ?
