Automatic Train Control

Automatic Train Control.

In recent years increasing attention has been paid by the Home railways to automatic train control, the Great Western Company being well to the fore in this activity. For nearly a quarter of a century the Great Western has steadily been extending its train control system, and very shortly the equipment will embrace 2,852 miles of track, 2,114 signalling locations, and 3,250 locomotives. The Paddington management favour a contact system of control, with a track ramp effecting contact with a shoe fitted under the locomotives. A new installation, now being tried out on the L. & N.E. Edinburgh-Glasgow main-line, employs what is known as the Hudd induction system of control. This system has, over a period of years, given very satisfactory service on the southern branch of the L.M. & S. railway, where 36 route miles of track are covered. Modern highspeed services call for every possible signalling refinement, and it seems likely that the L. & N.E. Company, interested as it is in high-speed running on all its main lines, will by degrees make automatic train control a permanent feature.
