As far as I know... It doesn't. I've been out to Spain during the summer when the temperature has been in cases unbearably hot. Yet the Alvia Train I was on between Madrid and Alicante still reached 155mph (Overhead Line Powered EMU▸ ). Similarly the Madrid - Murcia train I've caught during the Summer exceeded 100mph, don't have the exact GPS speed to hand. Train was a Diesel Locomotive and rake of coaches. |

Quite.
And Spain at least gets the low temperatures that we get also.
So get with it NR» .

As far as I know... It doesn't. I bet it does on some older lines. Either that or they have a more cavalier attitude to safety - perhaps the charge that NR are overly cautious could be levied though? Anyway, I expect HS1▸ is currently operating at 186mph as normal and, as yet, bar a couple of very short stretches FGW▸ has so far been unaffected. |

The part I find rather worrying is this (my bold): This is a problem that can affect all train operators. However, the ageing condition of our intensively used infrastructure means that even with the preparation work we have carried out, the infrastructure is unable to cope with the high temperatures we have seen during recent days which have reached almost 50oc on the tracks. As a layman, this sounds like the tracks have not been maintained and/or upgraded properly between the two stations. After all, why would the tracks between Clapham and Waterloo be any more prone to temperature damage than anywhere else on the network? SWT can't pin this onto Network Rail either, as they are now in a "deep alliance", as we keep getting reminded. |

Oh, I think they can....
That alliance hasn't been going long enough for their influence to achieve that major job....

I don't know what the linespeeds are in that area, but surely nothing goes that fast between Waterloo and Clapham Jct. anyway?

What fast? Can't see any mention of a specific limit. Just resultant cancellations....

According to the Standard, the speed limit is just 20mph. I think all trains usually manage more than that, even those stoping @ intermediate stations!

A stopper (at Vauxhall and Queenstown Rd) typically takes 10 minutes, with a distance of 3mi 74ch, gives an average speed of 23.55mph. Of course the train travels faster than this as the duration includes dwell time, so a 20mph speed limit would have a big impact.
My train (which runs non-stop Waterloo to Woking) should take 6 minutes to reach Clapham Junction. Today it took 12. The train managed to make up time and became on-time again at Fratton.

Either that, or our H&S▸ is extremely over-cautious.
