There are expansions joints but they are further apart.
Rails are stretched to limit that expansion in hot countries but if we stretched them they could fail in the very cold weather.
I saw a chart once showing how much they elongated for every degree hotter. It was incredible.
Right...........the "new" longer rails are also helping keep Scunthorpe Steel open (lost track of the name) they can make rails that are twice as long as anyone else....so less joints....and as the "welds" are a bit primitive (still using thermit reaction) they are stronger without the welds.That's pretty much what the said on the BBC News. They were having trouble with the overhead wires, they are normally tensioned by pulleys, but the expansion was beyond the set limits, so they just got slack.
31° pah!
I saw 39 in the van coming home last night at 6.30pm!
I went through a rain storm and it dropped 10° in a mile!!!
Oh I don't know, might put you on a high, read recently about the water sample from Westminster had a high content of the white stuff.Will never swim in Thames estuary again now I know what goes into it
Gosh.Yep Thursday spent the day shot blasting in the full gear.

It was hot yesterday. I was up in slim_boy_fats stomping ground. The pick up was recording 31 degrees. Air con was on full blast, lovely! Back up next week, bet it’s raining !
