3 years on British Rail

I spent 3 years sitting in a box on the Sussex Brighton Line. In my own compartment (and some of them even had pie heaters in them), and very little to do because of the Automatic Breaking System. The guards' job I suppose was to guard the guards' van. So, in the meantime, I got to do a lot of research into The I Ching. And that was a lot, on a thirteen day fortnight, since there was a shortage of guards for trains. Perhaps they were all prison guards, or in the Army.
