London, Sept, 27.
Ten years after its opening in 1927, the Post Office underground railway, built at a cost of £1,750,000 to expedite the transmission of mails, is justifying the foresight and faith of the committee which recommended it in 1909 by carrying an annual burden of 6,500,000 letter bags and 4,000,000 parcel bags, equivalent in the relief of street congestion to 750,000 motorvanmiles, Situated 70 feet below the streets of London, the railway operates,|automaticaly—its driverless trains carrying their loads of letters and parcels by day and night at an average speed of 25 miles an hour. The railway is 6% miles long and has eight stations, each connected with the main line railway station above. Each station is provided with &n up-to-date plant for the speedy conveyance of mailbags to and from the surface premises.
During busy night periods a continuous three minutes service, is maintained. When running, the trains are under automatic control and the arrangements of the dead conductor rail section between any two trains obviates all possibility of collision.
The power for working the railway is provided from two supply companies, so in the event of the failure of one source of supply the whole load can be switched over to the other.—Wireless through Reuter.
