Train Operation Systems
Train Operation Systems
Rising to the challenge of new forms of transportation in the ICT era.
We’re ensuring safe and stable transportation through
the optimization of trainset operation and operation control.
In addition, precise train control realized through combining onboard
and wayside equipment optimizes
energy consumption throughout the entire transportation system.
Automatic Train Supervision (ATS)
These systems enable centralized monitoring and control of train operation. User interfaces that offer superior visibility and operability enable accurate understanding of the status of train operation and rapid and precise command decisions. Diverse functions also assist in the formulation of operation plans.

Passenger Information Control (PIC)
LCD panels display train departure and arrival information, line information, advertisements, etc. Videos, still images and information in letters and characters can be freely combined.

Radio train control systems (ATACS*1/CBTC*2)
These systems enable trains to detect their own position, and enable control via two-way radio transmission between onboard and wayside equipment. In addition to making it possible to streamline wayside equipment (doing away with signals, etc.), cooperation between onboard and wayside equipment using advanced radio technology enables high-density operation, automatic operation and power-saving operation.

A signal security system developed by JR East
*2 Communication–Based Train Control System
Wayside equipment
Wireless technology enables position data and control data for each train to be exchanged, and control to be applied to the distance between trains, speed, route, etc.
The use of a failsafe processor ensures a high level of safety.

Radio equipment
A full lineup of radio equipment tailored to train control using the radio LAN band, the train radio band, etc. Ensures stable communication quality.
Onboard radio unit
Wayside radio unit
Onboard equipment
Obtains control data related to the interval between trains while transmitting position data for the subject train to wayside zone controller via radio communications, enabling ATO to be applied within a restricted speed.
