Products for Train Cars

Network-enabled In-train Security Camera System

This system records videos and allows them to be viewed in real-time in the crew’s cabin or control center. It can be easily upsized from stand-alone to network-based as needed.

LED Lights for Train Cars

We provide LED lights that complies with standards for train cars, both for new and existing cars.

Air Purifiers Equipped with nanoe X for Train Cars

Diffusion of nanoe X inside the train cars makes the air comfortable and clean. We offer a best installation method for each train car composition.

* nanoe and its logo are trademarks of Panasonic Holdings Corporation.

Tablet Connector for Train Car Announcement Equipment

By connecting a crew’s tablet to this device, voice announcements can be made inside train cars through such software as a foreign language guide app.

AVR67 power supply

This stably supplies electric power from the rolling stock side to the digital train radio, and also charges the backup battery at all times. The device consists of a constant voltage power supply, contactor box, switch panel, and battery. This is used for various types of rolling stock in the JR East service area.

Components of AVR67 power supply
(1) Constant voltage power supply, (2) With battery cabinet, (3) With battery tray, (4) Vertical switch panel type, (5) Switch box, (6) Contactor box

Jumper coupler for transmission

Information is transmitted between carriages via jumper couplers. The E235 series trains introduced on the Yamanote Line use the new INTEROS train information control system, which has increased the signal transmission rate through the jumper coupler from 10 to 100 Mbps (Ethernet standard). Therefore, a new jumper coupler that supports high-speed transmission was required, and we developed it. This jumper connector for transmission has been commercialized as a jumper connector that supports high-speed transmission of Ethernet standards and complies with international standards, and is used for the E235 series rolling stock on the Yamanote Line and the E131 series rolling stock for the Boso area.

LCD Units

We provide integrated LCD unit services from design to manufacturing, which can also include installation and modification.

Double-layered Gangway bellow

The diaphragm material is double-layered to improve durability and extend replacement intervals.

Fall-prevention outer canopy

The fall-prevention outer canopies are installed between carriages in order to prevent passengers from falling off the platform into the space between carriages. Due to its hollow structure, it can be flexibly deformed and restored to prevent damage.
There are two types of outer canopies: a fixed type and a detachable type that can be detached for roof-top inspections.

* Example of fixed type outer canopies
* Flexibly handles friction occurring on curves
* Flexibly handles friction occurring on curves

Motion prevention system

Signals forbidding the movement of rolling stock are given during rolling stock inspection and manufacturing operations, and safety is ensured by human confirmation, mainly through the use of flags or the installation of indicators and confirmation to the relevant personnel. When operated by a key, the motion prevention system electrically locks the powering circuit and main storage battery circuit, and displays that movement is prohibited (work in progress) inside and outside the rolling stock in order to prevent accidental operation of the rolling stock.

Products for Maintenance

Automatic Cleaning Machine for Train Car Air-conditioners

This machine automates the cleaning of train car air-conditioners, which is time- and labor-intensive, thus reducing workload and saving manpower.

Sanding Machine for Primary Suspension Plate

Rubber bearing spring vibration isolators prevent vibration when the train runs at high speed. Conventionally, rust that forms during train operation needs to be removed manually, but we have developed a machine that fully automates the sanding process for higher work efficiency.

Rolling stock washing facilities

We provide products that meet the needs of our customers, taking into account conditions at their location to ensure effective cleaning for various rolling stock.

Roof-top tread boards

This facilities is for safely climbing onto the roof of a carriage during pantograph inspections, and can be used for all types of rolling stock, both Shinkansen and conventional lines.

Parts washing facilities

We propose washing facilities suitable for various washing needs based on our extensive experience in rolling stock maintenance work.

Injection cleaning system for roller bearings

Injection cleaning system for traction motor parts

Wastewater treatment facilities

We propose eco-friendly wastewater treatment facilities that can be used for both new construction and replacement of old facilities, while taking into account life cycle costs.

Rolling stock lifting facilities

When replacing bogies, this facility synchronizes each piece of lifting facilities to raise and lower the rolling stock in the connected state. This facility can be used for all types of rolling stock, both Shinkansen and conventional lines.
