Dokodemo Door

Mitsubishi Heavy Industries Transportation Equipment Engineering & Service (MHI-TES) has developed a platform door system that can accommodate the operation of railway cars with varying numbers of doors for each car and door locations.

Dubbed as Dokodemo Door, the new door system will provide improved safety features and greater adaptability to shifting door locations when a train stops.

The system will feature safety measures such as detection sensors to sense people or their belongings and new projectors or LEDs in the door casings that contain built-in opening/closing mechanisms.

With this feature, warning messages are projected on the doors’ reinforced glass or displayed as LED-configured warning messages.

Moreover, the lineup of door types has been expanded with the development of pockets of minimal width, which enables the adoption of telescopic doors and also simultaneously permits wider door openings.

This platform door system will also be capable of accommodating larger variations in the train’s stopping positions, when used in combination with doors with casings, the company said.

Mitsubishi developed the Dokodemo Door system with the assistance provided by the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT) under its Railway Development Fund subsidy programme.

The Dokodemo Door is currently undergoing verification testing at the Wadaoki Plant of MHI’s Mihara Machinery Works in Hiroshima.

For the testing, the Wadaoki Plant has been outfitted with a mockup of a railway carriage and a platform-like space installed with a combination of doors with pockets and doors with casings, MHI stated.
