A Bit Of Hot Weather..

As I type, the outside temperature is apparently 26 degrees Celsius (which is almost 79 in Fahrenheit for those of us old enough to remember that scale). I'm just getting ready to go to work, but I know I'm going to be running late all day before I even start! How do I know this? According to the TfL disruption info, we have severe delays occurring due to temporary speed restrictions.

These restrictions were also imposed yesterday, which wasn't nearly as hot as today and are caused by the tracks apparently not being able to cope with the heat! This happens every year as soon as we get a bit of sunshine, as it's apparently to do with sections of long welded rail expanding (I'm no scientist!) but surely there must be a solution?

In the winter we get frozen points and the 'wrong type of snow', during wet weather we get track circuit and signal failures due to the damp, and in the summer we get buckling rails! This doesn't just affect LUL, I remember hearing similar tales of woe from the mainline too.

How do they cope in other countries which have extreme temperatures?

Anyway, I'll let you know what happened when I get in from work tonight!

There is - use shorter lengths of track with a small expansion gap, this is what gives the "chick-erty clack" but thats old fasioned, and not in keeping with this world class tube, world class city thing.

Maybe the Victorian did get somethings right?
