Tuberculosis

SETTING off for the City this week, I find that London Underground can offer me a choice, of a sort. No Circle line trains, owing to on-going signal problems and not, as I might think, the fact that the Circle line trains are the easiest to cancel. More signal problems on the Central line. Delays on the District and Hammersmith & City lines. Services on the Jubilee and Piccadilly lines are interrupted and, on the Bakerloo line, suspended. I take a taxi, and wonder what it would need to get the operators of this rail- way system to move over and let someone else have a go. We could begin with Project Dyno-Rod, my long-cherished plan for the Waterloo & City Line, or Drain. This fea- tures antimacassars and champagne (in Partner Class) and a train set so simple that we could rely on it, day in, day out. Now there's a funny thing: this morning, for all I am told to the contrary, the Drain would appear to be working.
