The 10.18 Chiltern Railways departure from London Marylebone is currently en-route to Birmingham Snow Hill.
Don't get on the third ("Quiet") carriage. The lights are off, plenty of people are sitting in it, and they've all got their coats on. The engine underneath the carriage isn't running and I suspect that unless the driver gets it started, the train will struggle to maintain time all the way to Birmingham.
*Perhaps Igloo isn't the most appropriate description - I understand that igloos are supposed to be surprisingly warm inside.
