You're hot then you're cold 3 8, 8:07pm

Meet the Dutch railways:

In summer, it's too hot and the rails expand, so they can't drive.
In autumn, there's leafs on the track which block the braking systems, so they can't drive.
In winter, the track switches freeze, so they can't drive.
And in spring, it's time for large maintenance, so yes, they can't drive.
