Method for substantiating the spheres of application of shunting locomotives at sorting stations

Shunting work on sorting wagons is carried out steeper profiles and requires the operation of shunting diesel locomotives a higher power. Many operations use double traction in conditions highly outdated fleet locomotives. However, technology operating two substantiation its scope application. In this article, using example station “X”, disbanding trains from hump investigated ways: first existing (work TEM-2 series), locomotive TEM-7 series. It has been determined that technology, required processing capacity hill approaches maximum value. When locomotive, increases by 27%. The sphere efficiency series instead was substantiated method technical economic calculations.
