Preserved Odakyu 3000 series SSE at Ebina depot (October 2007)

The Odakyu 3000 series (小田急3000形, Odakyū sanzen-gata) or SE (Super Express), later becoming SSE (Short Super Express), was a "Romancecar" electric multiple unit (EMU) train type operated by the Odakyu Electric Railway in the Tokyo area of Japan. It was the recipient of the inaugural Blue Ribbon Award presented by the Japan Railfan Club in 1958.

## Design

[edit]

The 3000 series trains were articulated with shared bogies, six of which were motored.[7]

## History

[edit]

Service first started in 1957 with the SE trainset, which, on a trial run, attained the world speed record at the time (145 km/h (90 mph)) for a narrow gauge train. This record gave impetus for the design of the first Shinkansen, the 0 Series.

This train adopted articulated bogies for comfort, efficiency, economy, and speed. This feature would be adopted by the NSE, LSE, HiSE, and VSE trainsets.

The 50th anniversary of the Romancecar's narrow gauge world speed record was celebrated on 28 September 2007.[8]

The trains were reformed from eight cars to five in 1968, becoming the 3000 series SSE (Short Super Express).

The SE trains were in service from 1957 to 1968, and the SSE from 1968 to 1991.
