Moonsoon halts London transport system

Says a lot on the state of our transport infrastructure...

I mean I understand (well not really but) that we can be un-prepared for meterological events that occur once every 5 years in average, like for instance snow. But rain, even when it's a lot?

But I can't comprehend how or why rain can still flood Richmond tube station (it's not underground!) or the M4 (elevated section).

The Department of Transport has a Dad's Army approach to infrastructure engineering: it's so bad it becomes farcical!
