The E1000 locomotive, commonly known as the PP Tze-chiang, is a series of electric push-pull trains used by the Taiwan Railways Administration (TRA), operated as part of the Tze-chiang limited express service. The locomotives were built by Union Carriage & Wagon and GEC-Alsthom, while the passenger cars were built by Hyundai Precision & Industries and Tang Eng Iron Works.

Push–pull is a configuration for locomotive-hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not.
