Tilting E353 to serve Chuo Main Line

27 Sep 2015

JAPAN: A pre-series Series E353 tilting EMU to operate Azusa limited express services on the eastern portion of the 1 067 mm gauge Chuo Main Line between Tokyo and Nagano has been unveiled by East Japan Railway.

The Series E353 sets are being built by the railway’s rolling stock subsidiary J-TREC, with exterior styling by industrial designer Ken Okuyama. Intended to replace the E351 units which date from 1993, the 1·5 kV DC sets have VVVF inverter controls and three-phase traction motors

Superseded for long-distance trips by the Tokaido Shinkansen, the 400 km inland trunk line between Tokyo and Nagoya was split following the break-up of Japanese National Railways. Today, JR East operates Azusa services east of Nagano and JR Central runs its Shinano limited expresses between Nagano, Nagoya and Osaka using ‘wide view’ Series 383 panoramic EMUs.

Whereas the E351s are formed of three-car and eight-car units coupled to form 11-car trains, the E353 has a base nine-car set with a three-car add on unit to permit 12-car operation. The three-car set has all cars motored with one powered bogie each, while the nine-car set has five powered cars and four trailers, including both driving vehicles.

All cars ride on bogies fitted with a pendular pneumatic swing suspension allowing operation at 130 km/h, while four cars have an ‘anti-rock’ active suspension. These are both driving cars and the green car in the nine-car unit and one driving car of the three-car set, to ensure that the end vehicles are always so equipped.

A 12-car set is designed to carry 656 standard and 30 green class passengers. LED lighting is fitted throughout, along with LED display screens providing passenger information. All seats are provided with power sockets and tables so that passengers can use their own laptops. 

Following commissioning tests, the new units are expected to enter service in the spring of 2016.
