If even one leaf falls on the line...

We have snow again. My Beloved attempted to go in to work. After nearly three hours and four miles the train broke down. I'm hoping he finds a taxi to bring him home, otherwise it's a long, cold walk.

The post title comes from the British comedy show Goodness, Gracious Me! where one character says of the English rail network

The people here believe the tree to be sacred, so that even if one leaf falls onto the track, the whole line is immediately shut down.

That isn't in this episode but there is a section about trains at around 23.00 minutes in that is pretty apt.
