If temp > 30°C then cancel trains

I got four cancellation SMSes yesterday evening, two of which were sent several minutes after the scheduled departure time.

Only a complete cretin buys trains to operate in a city where the temperature often exceeds 30°C that can't operate when the temperature exceeds 30°C!

It's a bit warm to be cycling home just at the moment, but it sure beats standing on the platform at Flinders Street wondering when the next train will show, only to find it's one of those battered old silver things with no aircon.
