Unfailing service for some of the world's busiest railways

Japanese railways handle some of the highest volumes of passengers in the world.
Complex schedules require some of the world's most precise operations.
And TEMS is right there as a partner company of JR East.
The top-notch maintenance we provide for all of our customers' equipment is part of what keeps Japanese railways running smoothly.

Unfailing safety and reliability

Signal equipment

In the railway industry, nothing is more important than safety and reliability. Signal equipment plays an integral part in this, including level crossings, ATS (automatic train stop) and the point machines that change the direction trains travel in. We carry out meticulous maintenance to keep this equipment operating perfectly at all times.

Unfailing communication

Communication equipment

Communication is critical in the railway industry.
Drivers and dispatchers need to communicate constantly with wireless devices, and any delays or cancellations need to be shown on a display. Our extensive maintenance of this equipment ensures that the necessary information reaches the necessary people every time, keeping rail services running smoothly and providing a stress-free experience for passengers.

Unfailing operation

Train line equipment

Trains run on electricity supplied by power lines. Without train line equipment, trains cannot run.
We make sure that all of our customers' train line equipment, including the trolley lines that the pantograph touches and the power poles that hold them in place, is perfectly maintained to ensure an uninterrupted supply of power across the wide area covered by our customers' services.

Unfailing station maintenance

Electric lighting and power equipment

It takes a lot of electric equipment to keep a station running, from lighting to signboards, elevators, escalators, ticket machines and ticket gates. And all of that equipment needs to be well maintained to keep it operating at all times and ensure the safety and comfort of everyone in the station.

Stations are taking on new roles and we are there every step of the way, supplying power to the equipment in the stations themselves and the adjoining shopping facilities.

Unfailing handling of electricity

Transformers

The power supplied by generators has an extremely high voltage. The transformers we maintain are used to convert it to power the equipment used for trains and in stations.

They are also used to prevent a fault in one piece of equipment from damaging other equipment.

Unfailing power supplies

Power supply equipment

The power supply equipment used by stations includes generators, transformers, power lines between the two and transmission towers.

Everything in the railway industry depends on this equipment, and we carry out thorough maintenance on a daily basis to provide the vital power that keeps everything running.
