The E235 series will be a renewal of the current E231 series (introduced in 2002). One of the key elements of the new model is that each car will have as many as 36 monitors with 20-inch LCD screens in place of the current hanging ads. Additional priority seating for the elderly and the physically disabled, as well as a “free space” for baby strollers and wheelchairs, is planned for all cars. The seats will also be widened from 45 cm to 46 cm, and LED lighting will be used. The stainless steel body will remain almost the same, but the pea-green horizontal stripes that symbolize the Yamanote Line will be removed. In their place will be vertical stripes on the doors only. To enhance safety, an improved monitoring system for tracking down malfunctions while the train is running will be added. E235 Series is scheduled to revenue in service by fall 2015.
