# Odakyu 30000 series EXE

The Odakyu 30000 series (小田急30000形, Odakyū 30000-gata), branded "EXE/EXEα" ("Excellent Express/Excellent Express Alpha"), is an electric multiple unit (EMU) train type operated by the private railway operator Odakyu Electric Railway in Japan on Odakyu Odawara Line and Odakyu Enoshima Line "Romancecar" services since 1996.

## Design

Seven 4+6-car trainsets (70 vehicles) were built between 1996 and 1999 to replace ageing Odakyu 3100 series NSE trains. Unlike earlier Romancecar trainsets, which used articulated carriages, the 30000 series sets have 20 m (65 ft 7 in) long bogie cars. The inner driving cabs of the 4+6-car formations have gangway doors.
The passenger doors use 800 mm (31 in) wide sliding doors, with 1,000 mm (39 in) wide doors on cars 2, 5, and 8 to provide wheelchair accessibility.

## Operations

The 30000 series trains are used on Odakyu Odawara Line Hakone services between Shinjuku in Tokyo and Hakone-Yumoto Station in Kanagawa Prefecture (about 88 km (55 mi)), as well as Sagami and Homeway services. They are also on Odakyu Enoshima Line Enoshima services between Shinjuku and Katase-Enoshima.
Trainsets were introduced on combined Hakone and Enoshima services, with trains dividing at Machida, and later at Sagami-Ono. 10-car Hakone services to Hakone-Yumoto also divide at Odawara with just the 6-car sets continuing onward to Hakone-Yumoto.

## Formations

### Refurbishment

The fleet underwent a programme of refurbishment from fiscal 2016, with the first 4+6-car trainset treated returning to service in March 2017, rebranded "EXEα".
Refurbishment was carried out by Nippon Sharyo, with the design overseen by Noriaki Okabe Architecture Network. It includes the following changes:
* Redesigned interiors and seating
* Replacement of Japanese-style squat toilets with Western-style toilets (Toto "Washlet" type)
* Additional luggage racks
* LED lighting in passenger saloons
* Installation of security cameras in vestibule and passenger saloons
* Fully enclosed traction motors
* Conversion of one former trailer car (car 3) to a motored car, and the addition of a second motored bogie to car 9, which previously only had one motored bogie.
The first train set to be refurbished, four-car set 30051, was returned to Odakyu from the Nippon Sharyo factory in Toyokawa, Aichi, in November 2016.
* A refurbished "EXEα" set in November 2021
* The updated passenger saloon interior in April 2019
