The 1990s saw more rapid development and changes within the railway. The Kowloon-Canton Railway Corporation (KCRC) signed a contract with Anglo-French manufacturing giant GEC-Alsthom to refurbish the Metro-Cammell EMUs at the East Rail depot at Ho Tung Lau. In 1996, the first refurbished train was put into service, and trains now allow passengers to traverse from one end to another (except for the first class carriage), when trains once ran on four three-car EMUs. All but three of the 351 railcars were refurbished; the only unit exempt from refurbishment was unit E44 (144-244-444), which is currently stored in Ho Tung Lau depot. Each set is still made up of 12 cars (with one first-class car). Prior to the rule proclaimed in 1994 which fixed the number of cars on each set to 12, trains were inconsistent in terms of length, ranging from six cars (two EMUs), nine cars (three EMUs) to 12 cars (four EMUs).
