caption_attribution_description: English: FCAB EMD GR12U 1403 and EMD/Clyde G22 1435 are working hard as mid-helpers to get a long rake of loaded sulfuric acid tank cars and empty flatcars up cumbre pass. Between Pampa and Cumbre, Chile. Deutsch: Die Zwischenloks EMD GR12U 1403 und EMD/Clyde G22 1435 arbeiten schwer, um eine lange Reihe Schwefelsäure-Kesselwagen und Flachwagen den Cumbre-Pass hoch zu kriegen. Zwischen Pampa und Cumbre, Chile.
context_page_description: In rail transport, distributed power is a generic term referring to the physical distribution—at intermediate points throughout the length of a train—of separate motive power groups. Such 'groups' may be single units or multiple consists, and are remotely controlled from the leading locomotive. The practice allows locomotives to be placed anywhere within the length of a train when standard multiple-unit operation is impossible or impractical. DP can be achieved by wireless or wired means. Wired systems now provided by various suppliers use the cabling already extant throughout an ECP train.

Such 'groups' may be single units or multiple consists, and are remotely controlled from the leading locomotive. The practice allows locomotives to be placed anywhere within the length of a train when standard multiple-unit (MU) operation is impossible or impractical. DP can be achieved by wireless (RF connectivity) or wired (trainlined) means. Wired systems now provided by various suppliers use the cabling already extant throughout an ECP train.
