Kobe City Transportation Bureau’s new ‘6000 series’ for the Seishin Yamate subway line

The Seishin Yamate line of the Kobe City Subway connects surrounding new towns with the city, making it an essential means of transportation for people living there. This area has many hills and valleys, meaning the railcar couplings get pushed and condensed by vertical and horizontal forces during operation above ground. In order to ensure protection against these forces, HARTING jumper cables installed on the Kobe City Transportation Bureau’s new ‘6000 series’ for the Seishin Yamate line underwent rigorous tests for durability, including stretching and condensing from the stationary state and curve and S form curve testing from the straight line. HARTING’s own facility is accredited to ISO/IEC 17025, the international laboratory standard, which enables the company to conduct these tests in-house and issue test reports.

Intercar Jumper Cable

HARTING’s inter-car connectivity solutions consist of cables and a rectangular, modular industrial connector which is designed for use in harsh environments. These robust solutions, which are protected against dust and water ingress, corrosion, high voltages and electromagnetic interference, were adopted for all inter-car lines of the Kobe City Transportation Bureau’s new ‘6000 series’ for the delivery of data, signals and power. The inter-car connections of the new train use the established Han® HPR housing individually for data, signals and power. Data connection with Ethernet modules was installed for onscreen passenger information services in four languages, video and control. Modules and monoblock inserts for signals and power are used
for control circuits and main circuits. Kobe City Transportation Bureau’s new trains consist of six railcars running on the Seishin Yamate line. It adopts the design determined by a citizen’s ballot and was constructed by Kawasaki Heavy Industries. In February 2019, two trains started operation. All 28 trains are planned to replace the existing ones by March 2023.
