The New London Underground Railway.
HOW the. road-bed is being used /so* START AND HTQP THE. J
Jn designing the new London under-' ground railroad the engineers have hit upon a new scheme which atter be adopted,- on surface roads. There are no grades in. the tunnel, but at various points th© road-bed itself has been inclined so* that it can be used as a brake car as- a speed accelerator for trains. On each side elf each station is a S per cent, gradient, rising on the approaching side; and falling again to the level of the road on the departing side This- unique method gives a retarding effect to all trains approaching the stations equivalent to the application of considerable additional braking power, while materially aiding in the acceleration of all' trains as they leave the platforms. Furthermore, the saving in power necessary' to secure the rapid acceleration is .adoption of. this plan calculated to amount to about 33 per cent; This is a point in modern railway practice, which might well be adopted by surface roads.
