Keio Corporation has built a new set of 5000 series rolling stock fi tted with seats that are reconfi gurable to suit diff erent types of train operation, with longitudinal seating for nor- mal operation and cross seating on trains that use designated seating. Th e rolling stock com- menced operation on September 29, 2017 on the Keio Line where they are being used for conventional services. Trains with designated seating available for purchase will be introduced 5 20000 series rolling stock for Sagami Railway (top) and first in the spring of 2018.

Hitachi also developed and installed integrated safety equipment that is able to adapt fl exibly to the safety functions expected to be used for through-train services. Th e design of the rolling stock followed the design concept from the design brand upgrade project of the Sotetsu Group, using Navy Blue, the new feature color for the Sotetsu Main Line, for the exterior. For the interior, the rolling stock were the fi rst to use universal design seats developed by Hitachi to be easy to get into and out of, these being used for some of 6 Traction storage battery pack (top) and Keio Corporation the priority seating.
