The E993 series (E993系) "AC Train" was an experimental 5-car electric multiple unit (EMU) train operated by East Japan Railway Company (JR East) in Japan between 2002 and 2006.[1][2]
Concept
The E993 series "AC Train" ("Advanced Commuter Train") was developed by JR East to test and evaluate a number of new technologies and features for possible use in future commuter train designs.[1] These included features intended to reduce life-cycle costs, improve the interior passenger environment, improve accessibility, and increase environmental friendliness.[2]
Technological features
The train incorporated the following features for evaluation.[2]
- Articulated cars with shared bogies
- Direct drive motors (DDM)
- Double-skin body construction
- Externally slung sliding doors
- Advanced Train Information Management System (AIMS)
Formation
The 5-car articulated set was based at Kawagoe Depot on the Kawagoe Line and formed as shown below, with car 1 at the Kawagoe end, and car 5 at the Shinjuku end.[3] Cars 1 and 2 were built by Kawasaki Heavy Industries in Kobe, and cars 3 to 5 were built by Tokyu Car Corporation in Yokohama.[2]

History
The train was delivered to JR East's Kawagoe Depot on 17 January 2002.[2] Test running commenced on the Kawagoe Line and Saikyo Line the following month.[2]
The train was officially withdrawn on 14 July 2006.[4]
Features tested on the E993 series, including articulated cars and direct drive motors, were subsequently incorporated in the E331 series prototype train delivered in 2006.
