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]
| Car No. | 1 | 2 | 3 | 4 | 5 |

| Designation | Tc' | M' | M | T | Tc |
| Numbering | KuHa E992-1 | MoHa E992-1 | MoHa E993-1 | SaHa E993-1 | KuHa E993-1 |
Cars 2 and 4 were each fitted with one single-arm pantograph.[3]
Cars 1 and 2 had double-skin aluminium bodies, cars 3 to 5 had stainless steel bodies with double-skin construction used for cars 3 and 5.[2]

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.
