It was a quote from virgin radio this morning "trains in the south east are havng timetable problems due to the wrong kind of sun" I think it was meant in jest
You would think that they would design as railway to not buckle in the heat, the friction off a train going 125 miles per hour must cause some heat in itself!!!

The term "The wrong kind of sun" is a sarcastic quote, referring to the trouble when we had particularly powdery snow, which was hard to clear from the track, hence the quote "Wrong kind of snow". Obviously the sun is the sun at the end of the day. As for building train tracks which can withstand the heat, when the majority of the tracks were built many decades ago, it was never as hot as it is these days. The problem isn't in the building as such, it's in the underinvestment over several governments since the 70's.
