Electrical equipment for rail use

Train air conditioning system

Train depot systems

Maintenance information
management system (MIMS)

Centralized management of train equipment logs and train data, including maintenance data and malfunction data, in a database. Supports expansion to use in malfunction prediction and improvement of maintenance procedures.

Depot information
management system (DIMS)

Formulates train operation (allocation) plans based on main line timetables and train maintenance plans. Can also be used in the formulation of depot work plans and route control.

Measurement and analysis of wayside equipment.

Mitsubishi Electric’s MMSDTM* infrastructure monitoring system enables measurement and analysis of wayside equipment using measurement cars

Using high-precision 3D measurement and a range of sensing technologies, we are able to automate social infrastructure inspections and equipment measurements, reducing the expenditure of manpower and increasing precision. Conducting measurements in motion using road-rail vehicles and similar equipment makes it possible to conduct precise 3D measurements in a short period. Analysis and processing of 3D shape data enables its use in a variety of fields and applications.
