Introduction of subway vehicles

This is the first municipal subway train. Initially, it was manufactured with three cars per train. Finally, we produced 84 cars in total of 14 trains. In December 2006, except for the first train three cars (the first vehicle manufactured), it was scrapped. The first organization is preserved at the Niwa Depot.

The 2000 type, which was manufactured in line with the Shin-Yokohama and Tozuka extensions, is the first air-conditioning vehicle in Kanto. It is more durable than 1000 for all stainless steel vehicles. In addition, since it is a regenerative vehicle, we have saved energy compared to the 1000 model. As with the 1000 model, a total of 9 trains and 54 cars were scrapped at the end of December 2006.

In the 3000A shape, a total of 48 cars were manufactured in accordance with the Azamino Line extension. It is equipped with a VVVF (variable voltage variable frequency) control device to save energy to more than 2000 models. In addition, it is equipped with a train control management device, and the control and management of electrical equipment of the vehicle is centralized with a computer, making maintenance easier.

Along with the extension of the Shonandai Line, a total of 42 cars were manufactured based on a 3000A type vehicle. The basic performance is almost the same as that of the 3000A type vehicle, but in order to improve customer service, we have made news and commercial broadcasts on the in-vehicle information display. In addition, we have expanded the seat width so that customers can ride more comfortably, and have improved the details such as installing large sleeve partitions.

With the abolition of the 1000-type vehicle, a total of 84 cars in 14 trains were manufactured. We have been making barrier-free compared to conventional vehicles, and we have installed wheelchairs and strollers spaces in all vehicles to reduce the gap between the platform and the floor. In addition, the height of the hanging leather has been reduced to two types, and the seat seat has been turned into a bucket so that customers can ride comfortably.

With the abolition of the 2000-type vehicle, a total of 48 trains were manufactured. The car body part is the same as the 3000R type, but we worked to reduce costs by using some of the scrapped 2000 parts (trolleys, automatic train control devices, auxiliary power supplies, brake devices, etc.).

In March 2017, a total of 6 cars were manufactured as a pre-manufactured vehicle following the renewal of the 3000A type. Following the barrier-free facilities of the 10000 second-order car, the first blue-line vehicle in-vehicle information display was installed, and unlike the previous image, the interior of the guest room is colored based on blue. In addition, we use high-efficiency control equipment, electric motors, and LED guest room lights to enhance driving safety by promoting energy conservation and monitoring functions through the use of PQ monitoring trolleys.

Based on the concept of "advanced urban feeling of the seaside", the design is designed to give a dignified appearance and a sense of speed. In terms of functionality, in addition to improving barrier-free and comfort, safety has been improved, including the introduction of the security camera. It has been in operation since May 2022 as an alternative to the 3000A model.

We manufactured a total of 60 cars of 15 trains as vehicles for the Municipal Subway Green Line (Subway Line 4), which opened in March 2008. The biggest feature is that it is a linear vehicle that can run steep and steep curves, which is a characteristic of the Green Line route. In addition, because it is a small vehicle, the cross-sectional area of the tunnel was small, and construction costs were reduced. In addition, we are working to improve customer services by installing two LCD-type in-vehicle information signs at the top of the side sliding door for the first time as a municipal subway to make the car barrier-free as a 3000R type vehicle.

Thanks to the Green Line, the use of customers has steadily increased, and it is no longer possible to respond with 15 trains, so we have two Narimasu. (10000 type 2nd car) The basic design of this vehicle is the same as the primary car, but with the aim of further energy saving and barrier-free, the in-vehicle information display was converted into four languages, door opening notice lights and yellow belt tapes were installed on the side door, and LED lighting was installed.
