The Bombardier Electrostar, a model of train common in South East England, was selected for the system. Fifteen cars were manufactured and were assembled by Bombardier's Derby Litchurch Lane Works in England, with the remaining cars assembled by the Union Carriage & Wagon in South Africa using structural components made in England. Gautrain has 24 trains, each made up with four cars: 19 trains service the commuter network and five the airport link; the latter consists of forward rail cars specially adapted for the airport link; with storage area for luggage and more luxurious seating.
