As others have already explained, the rest of Europe stresses its
long-welded rail within different parameters, appropriate to the
standard weather conditions in the country concerned. Nevertheless,
the UK is not the only country suffering from restrictions due to
weather conditions beyond the expected norm

So which ones are exactly? Spain, France, Germany, Portugal have no
problems at all on their rail systems. So which ones have problems? And
what problems? And is it the heat causing them?

SNCF have been reporting quite a few heat-related problems on their
website over the past few days. It was reported in news:uk.railway that
a TGV was derailed on Wednesday due to a buckled rail.

Or do you think just because the UK media doesn't report something it
doesn't happen?
