Faster··· Safer··· More comfortable··· More beautiful··· The train carries boundless dreams. In pursuit of dream trains, Taisei has been, ever since its foundation, dedicating itself to the design, manufacture, and maintenance of a wide range of systems and components for railway vehicles. Taisei's expertise can be found not only in core electric units such as under-the-floor equipment crucial to safety operation but also in amenity systems for the comfort of passengers such as air cleaners and ozone-based deodorizers. For example, the air cleaner installed on the rack of a double-decker car of Model E4MAX Shinkansen brings comfort to long-hour commuting during rush hours. What's more, the roll filter integrated in the air cleaner and the heater with a circulating fan further enhance the comfort of JR trains. Taisei is contributing its long-substantiated expertise and fresh ideas to the development of tomorrow's trains, thereby passing childhood dreams on to the next generation.

To maximize the comfort of train rides by removing unpleasant odors, fluffs, and tobacco smoke, Taisei develops a variety of amenity equipment such as air cleaners, ozone-based deodorizers, roll filters, and heaters with a circulating fan.

On order from electric manufacturers or Japan Railway companies, Taisei designs and manufactures a variety of electric equipment to be installed under the floor of the passenger car.

When it comes to the maintenance, repair, and upgrade of train vehicles, Taisei is at your service, ready to dispatch engineers around the clock.

Taisei offers a wide range of facility supporting equipment, such as the operation simulator for training motormen, the dumper tester for measuring the dumping performance of the shock absorber, the loaded motor tester for testing motors under loaded conditions, the filter cleaner for automatically cleaning the filters in the air cleaner, the tester for relays installed underneath the floor, and the vehicle main switch on/off indicator which, during the maintenance of the passenger car in the maintenance yard, sends radio signals from the car.
