Japan Transport Engineering Company

Japan Transport Engineering Company (J-TREC) (株式会社総合車両製作所) is a manufacturer of heavy rail cars in Japan, formerly known as Tokyu Car Corporation (東急車輛製造株式会社). The company is based in Kanazawa-ku, Yokohama, and a member of East Japan Railway Company (JR East) group. J-TREC manufactures rail vehicles not only for JR East and Tokyu Corporation but for other Japanese operators, including various Japan Railways Group companies and international operators as well.

Tokyu Car Corporation, the predecessor of J-TREC, was founded on 23 August 1948. Tokyu Car was a licensee of early-generation (early-1960s) stainless-steel commuter EMU train body and related bogie technology from the Budd Company of the United States. Since then, Tokyu Car has specialised in stainless-steel body car technology.

On 27 October 2011, Tokyu Car Corporation announced that its rolling stock manufacturing division would be acquired by East Japan Railway Company (JR East), and the company cease operations with effect from 1 April 2012. It is to be subsequently split into two companies, Tokyu Car Engineering and Keihin Steel Works. Both companies will be subsidiaries of JR East. The remaining parts and machinery manufacturing division was subsequently sold to ShinMaywa Industries.
