Take on the trains

The temperature topped 90 degrees which apparently means that the trains can't run anymore. I don't get the issue but I'm sick and tired of people telling me how good train service is and how we should be expanding it when a little heart wave shuts it down.
I don't even take the train and I'm annoyed by it…mostly because it forced a billion extra people onto the roads and tunnels and turned my usual horrible bus commute into a downright miserable one.
