TX-1000 series

The TX-1000 series (TX-1000系) is an electric multiple unit (EMU) train type operated by the Metropolitan Intercity Railway Company on the Tsukuba Express line in the Kantō region of Japan since 2005. A total of 84 cars were delivered.

Design
The TX-1000 series trains use unpainted double-skin aluminium body construction assembled with friction stir welding. They are used only on the Akihabara – Moriya section of the Tsukuba Express line, which is electrified at 1,500 V DC, as the rest of the line is electrified at 20 kV AC; services beyond Moriya to Tsukuba are operated by dual-voltage TX-2000 series sets only.

Formation
Car 2 is fitted with one single-arm pantograph and car 4 is fitted with two.

Interior
Passenger accommodation consists of longitudinal bucket-style seating throughout.

History
The first 6-car prototype was built in March 2003 by Kawasaki Heavy Industries, and 13 more sets were subsequently delivered between March 2004 and January 2005.
