I'm finally back to work on a sort of occasional, restricted hours basis. I dare not travel in the rush hours because it is essential that I have a seat, and avoid all risks of anyone standing on or kicking my injured foot, on the 50 minute journey 'twixt beautiful Ruislip and Waterloo. And the effort of getting to work, as well as being there, is very tiring. So I'm doing a few hours, every three days or so, and working as much as possible at home the rest of the time.
It is quite pleasant to travel down mid morning in trains barely half full. Coming home they seem to be crowded no matter what time I choose to depart. But actually the idea of the "rush hour" is very out of date. Huge numbers travel at all times, apart from very early and very late. I can recall when the evening trains would be full of suited men with briefcases rushing home to their dinners in the suburbs (Thank you Mr Betjeman, we'll let you know: Ed). There are a few left, of course, but the travelling public is now representative of the general public, and in world that increasingly works all hours and all days, the transport system is going to do the same.
