News reports from Southern England state rails are buckling due to the heat. It would appear to an American that 80-degree or 90-degree weather shouldn't have any effect, but I don't think their expansion joints, if they have them at all, are prepared for such. 90 degrees here yesterday. Okay, Summer's a little bit early. 90 degrees there? It's the end of the world.
