 The fast, frequent service resulting from the introduction of the first generation of electric trains in 1931 was a significant contributor to suburban development in the Stretford, Sale and Altrincham districts, south-west of Manchester.The southern part of the MSJ&AR's route has been part of the Manchester Metrolink light rail system since 1992.The northern section between Manchester Piccadilly and Deansgate stations is now an intensively-used section of the National Rail network, used by trains running north and west of Manchester.
