USE OF THE LINEAR MOTOR IN MARSHALLING YARDS

The linear motor seems destined to become an auxiliary in the automation of marshalling yards. The above article summarises the results of the studies carried out with models, and the tests made on vehicles, of the three principal types of equipment, using: (1) the linear motor accelerator-retarder (L3); (2) the electro-magnetic accelerator (L5); and (3) the electro-magnetic retarder (L6). The L3 is a fixed device using the periphery of the wheel as a secondary armature. The L5 feeds into the rails strong dc or ac, whose magnetic field moves the vehicle at the required speed. The Lfound brakes the wheels or means of the magnetic field which exists between the brake shoes. A description is given of the test equipment used, the cross sections of the three devices are shown, together with diagrams setting out the results, and the conclusion is reached that: (1) the Lc would have all the necessary advantages, but lacks accelerating power, and is not altogether ready; (2) the L5, reinforced by means of a feeder, is capable of making use of very strong current, but its power of accelerating decreases rapidly as the speed increases, thus restricting the latter; and (3) the L6 ensures excellent braking, and can be brought into service.
