It is a part of the Eastern Kanagawa Rail Link strategic plan for improving the rail network connectivity of Kanagawa Prefecture. The railway line's infrastructure is maintained by the Japan Railway Construction, Transport and Technology Agency (JRTT). Tōkyū collects the operation revenue and pays JRTT for using the rail infrastructures, then JRTT use this payment to maintain the infrastructures and reimburse the loan for the construction of this line.[2]

The Tōkyū Shin-yokohama Line opened on 18 March 2023.[3][4]

Summary

The entire line runs between Shin-yokohama and Hiyoshi. A new intermediate station, Shin-tsunashima, is situated near Tsunashima Station on the Tōkyū Tōyoko Line.

Sōtetsu Shin-yokohama Line trains run through service with Tōkyū, Tokyo Metro, and Toei Subway Lines via Shin-yokohama.

Shin-yokohama Station is jointly operated by Tōkyū and Sōtetsu. This is the first case for both operators to have a station with direct connections to the Shinkansen.

Routes and services

Beyond Hiyoshi, trains head towards Shibuya via the Tōkyū Tōyoko Line or Meguro via the Tōkyū Meguro Line.

In mid-2022 it was announced that through service trains to the Tōkyū Tōyoko Line could continue along the Tokyo Metro Fukutoshin Line to Wakōshi and further on the Tōbu Tōjō Line. However, trains would not be allowed to run through on the Seibu Yūrakuchō & Ikebukuro Lines and must transfer at Kotake-Mukaihara Station. Beyond Shin-yokohama and Nishiya, Tōyoko Line express trains will run via the Izumino Line to Shōnandai station.

It has been proposed that the Tōkyū Shin-yokohama Line operate 14 trains per hour during rush hours, with 4 heading to the Tōyoko Line, and 10 heading to the Meguro Line. Meguro-bound Shin-yokohama Line trains will operate through services not only to the Meguro Line, but also the Toei Mita Subway Line and Tokyo Metro Namboku Line, with further service onto the Saitama Rapid Railway Line. Once connected to the Sōtetsu network at Shin-yokohama, Meguro line trains will run express along the Main Line to Ebina station.

In 2016, Toei announced that thirteen of its 6300 series trainsets (1st and 2nd batch) would be replaced, and in 2019 nine new trainsets compatible with the Sōtetsu Line would begin service, with more trainsets to be produced until 2021.[5] In 2018, they ramped up their plans and announced that 13 new trainsets with the same designation numbers as the 13 that are replaced would be introduced to service.[6] These new models are formed as 8-car sets[7] made by Kinki Sharyo and classified as 6500 series.[8] The first of these sets entered service on 14 May 2022.[9] Meanwhile, the 3rd batch of 6300 series trainsets will continue their service on the Mita Line, but they will still be upgraded to enable compatibility with the Sōtetsu Line, by introducing digitized communications equipment and the ATS-P system.[10] With Mita Line trainsets extending to 8 cars, Sōtetsu is undergoing preparations to enable compatibility with 8-car trains.[11] Additionally, Sōtetsu has also introduced its 20000 series developed for use on Tōkyū through services;[12] the type first entered service in February 2018.[13]

Station numbers for the Tōkyū Shin-yokohama Line between Shin-yokohama and Hiyoshi were revealed on 16 September 2022.[14]

Through the end of 2022, various trainsets from Tōkyū, Sōtetsu, Tokyo Metro, Toei, and Tōbu conducted tests along the now completed segment of this line and the Sōtetsu Shin-yokohama Line between Hiyoshi and Hazawa Yokohama-Kokudai.

On 16 December 2022, Tōkyū, Sōtetsu, and the Japan Railway Construction, Transport and Technology Agency announced that the Tōkyū Shin-yokohama Line would open on 18 March 2023. The Sōtetsu Shin-yokohama Line section between Shin-yokohama and Hazawa Yokohama-Kokudai also began serving at the same time.[4] The Shin-yokohama Line opened as scheduled on 18 March 2023, providing through service between Shin-yokohama and Hiyoshi.[15]
