Japan railway to design first freight-only bullet train car to boost deliveries

According to The Asahi Shimbun, East Japan Railway Co. plans to develop a cargo-only car—and possibly an entire train—for its Shinkansen services to increase freight transportation capacities, offering a speedy and expanded delivery service.
JR East, which operates the Tohoku, Joetsu and Hokuriku Shinkansen lines, is considering incorporating around two cargo-only cars into a train, company sources said.
The freight-only cars will have no passenger seats and feature larger doors that allow for smoother loading and unloading operations.
In the future, the company may introduce a Shinkansen consisting exclusively of cargo-carrying cars, the sources said.
