History
Multiple-unit train control was first used in Electric Multiple Units in the 1890s. This allowed electrically-powered rapid transit trains to be operated from a single driving position. Early users of such multiple units include the Liverpool Overhead Railway (the first multiple units) and Chicago's South Side Elevated Railroad (the first units to use a low-voltage control system).
