IN order to protect railway and road transport services from the risks arising from air raids, London Transport, in conjunction with the Ministry of Transport, has undertaken a great programme of emergency work. The Electrical Times of October 19 states that the total cost of the programme, including that already completed at the outbreak of the War, will be about a million pounds. The most difficult part of the problem was how to protect the underground railways from flooding either from the Thames itself or from sewers or water mains where these are in close proximity to stations. There has been already a preliminary inspection of two examples of such protective works, namely, floodgates installed at Waterloo, where the tunnels of the Northern line go under the river, and work which has been done at King's Cross Underground, to guard against flooding from water mains and sewers. When the works are finished, all the stations and sections of line at present closed will be reopened and journeys on the Underground will be as safe as in peace time.
