Products
Onboard Train Systems
A system integrator that provides powering, braking, control and comfort functions —all from one single company.
Mitsubishi Electric delivers overall optimized control for train systems by incorporating the Train Control and Management System (TCMS) as the main component. Our creation of system platforms for the collection and utilization of train monitoring data in cooperation with wayside equipment enables us to also realize CBM*1.

Train Control and Management System (TCMS)
Propulsion Systems and Power Supply Unit
Propulsion control and power supply unit that incorporates leading-edge inverter control. We support safety and comfortable operation with proven AC motors and drive equipment in addition to the latest technologies.
VVVF Inverter
Using SiC, the next-generation device, we have realized reduced power consumption, as well as reduced volume and mass.
Traction Motor
Reduced noise, maintenance-free cleaning, and shorter maintenance time thanks to cartridge bearing housings.
Gear Unit
The use of a vertical suspension configuration simplifies maintenance and assembly. Test verification in comprehensive test facilities ensures complete reliability.
Low-noise WN Coupling
Optimal tooth shape design ensures reliability while realizing low noise even when coasting.
Brake Control Unit, Security Equipment, and Automatic Train Operation
We support safe train operation via brake control unit manufacture with a history of more than 90 years standing behind it, reliable failsafe technologies, and automatic operation technologies.
Brake Control Unit
A standard-type brake control system that is smaller and lighter than conventional models, with improved maintainability.
Integrated Security Device
Apply to multiple signal systems like ATS*2, ATC*3 and communications-based train control (CBTC), etc.
*2 Automatic Train Stop
*3 Automatic Train Control
Automatic Train Operation (ATO)
A learning function increases ride comfort and the precision of stops, while predictive control for busy periods realizes energy-saving operation.
Services and Security Equipment
We contribute to improve passenger services with air conditioning considering both people and the environment, and image display incorporating the latest information technology. We also work to enhance onboard security.
Train Vision (Passenger Information System)
High-definition videos and animation displays boost advertising value.
Onboard Crime Prevention Systems
High-resolution cameras monitor and record every part of the train, deterring crime. Functions can also be expanded to live display of the driver’s cabin, etc.
Linedelier (Linear Fan)
Contributes to increased air conditioning efficiency by directing air across a wide area of the train interior.
HVAC (Air Conditioning)
Multiple temperature sensors allow the onboard environment to be controlled to a comfortable ambient temperature.
HVAC (Air Conditioning) (Shinkansen)
Compressor controlled by inverter enables fine control of onboard temperature.
HVAC (Air Conditioning) (R290 / Natural Refrigerant)
Use natural refrigerants to protect the environment and ensure supply stability.
Meet European standards to deliver safe and sustainable railway air conditioning.
Inverter/Converter and Traction Transformer
Our inverter/converters and traction transformers leverage advanced technologies cultivated through Shinkansen development to support the stable operation and high efficiency of rail vehicles.
Inverter/Converter
The use of SiC*4 module reduces size and increases efficiency.
*4 Silicon Carbide
Traction Transformer
Saves energy, minimizes maintenance and reduces noise with a natural air cooling system.
Traction Transformers for High Speed Railways
A proprietary configuration reduces oil use in addition to realizing reductions in size and weight; we have also worked to reduce the necessary maintenance.
