Sotetsu 9000 Series Rail Car Redesign
Boldness was required to create a uniform impression for the redesign of the railcars, due to the mixed use of new and old parts. A big design composition was done by painting the whole exterior with metallic blue, specifically named the YOKOHAMA NAVY BLUE, and completely renewing the colors for the interior. The train handle and the partition were designed completely from scratch, deeply considering safety and comfortability. Genuine leather was used for the seat covers on the transverse seating bays, to ensure the enhanced quality in areas where passengers have direct contact. The lighting temperature transitions as the time shifts from day to night.
