Tokyu Corporation will begin commercial operation of the 5-car “6020 series” trains for local trains on the Oimachi Line from July 2 (Wed), 2025, gradually replacing older trains that are becoming increasingly worn out.
7-car express and 5-car local trains
On the Oimachi Line, express trains began operating in March 2008 to strengthen the bypass function of the highly congested Denentoshi Line. The 6000 series, which was introduced as an express-only train, was originally a 6-car train, but by February 2018, all were upgraded to 7-car trains to alleviate congestion. In addition, two new 7-car 6020 series trains were added for express use from March 2018.
On the other hand, due to the length of the platform, local trains are still operated as 5-car trains, and the 9000 series, including trains transferred from the Toyoko Line, and the 9020 series, which was modified from the former 2000 series on the Denentoshi Line, continue to operate. These cars are over 30 years old, and the plan is to replace them all with 5-car 6020 series cars, 18 of which will be introduced by around 2027, for a total of 90 cars. The first train (6151), which will begin operation on Wednesday, July 2nd, will have a commemorative headmark in the form of a sticker designed by Oimachi Line crew members until around December.
Front and side stickers to prevent passengers from boarding the wrong train
The 6020 series is a new type of train that joins the “2020 series” along with the “2020 series” on the Denentoshi Line introduced in 2018 and the “3020 series” on the Meguro Line introduced in 2019, and focuses on improving comfort inside the car. To make it easier to distinguish from the 6020 series express trains, which have the same appearance, a “5CARS” sticker will be displayed on the front of the leading car to identify it as a 5-car local train, and a blue vertical sticker will be affixed next to the door on the side of the car to prevent passengers from boarding the wrong car.
By the way, Seibu Railway plans to take over VVVF inverter-controlled vehicles that were used by other companies, calling them “sustainable cars,” and to increase the ownership rate of energy-saving rollingstocks together with newly built ones. The first batch of sustainer cars are the 8000 type cars transferred by Odakyu Electric Railway, which have been remodeled and renewed and have been put into service as the Seibu 8000 series since Saturday, May 31. The Tokyu 9000 series cars, which will be replaced by new cars on the Oimachi Line, are also scheduled to be transferred as the second batch of sustainable cars, with three trains scheduled to be transferred to Seibu during fiscal 2025.
