The TX-2000 series (TX-2000系) is a dual-voltage electric multiple unit (EMU) train type operated by the Metropolitan Intercity Railway Company on the Tsukuba Express line in the Kanto region of Japan since 2005.[1]

## Design

[edit]

TX-2000 series trains are capable of operating on both the 1,500 V DC and 20 kV AC sections of the Tsukuba Express, and therefore operate over the full length of the line. (The DC-only TX-1000 series sets are restricted to the Akihabara – Moriya section of the line.)[2]

## Formation

[edit]

As of 1 April 2016[update], the fleet consists of 23 six-car sets (51 to 73), consisting of four motored (M) cars and two trailer (T) cars, and formed as follows with car 1 at the Tsukuba (northern) end.[2]

Numbering  | TX-2100 | TX-2200 | TX-2300 | TX-2400 | TX-2500 | TX-2600
Capacity
Total/seated  | 147/48 | 158/51 | 153/60 | 153/60 | 158/51 | 147/48
Weight (t)  | 30.3 | 38.1 | 34.4 | 38.3 | 34.3 | 30.9

Cars 2 and 4 are each fitted with two single-arm pantographs.[2]

## Interior

[edit]

Passenger accommodation primarily consists of longitudinal bench seating.[3] The middle two cars, 3 and 4, were built with transverse seating bays with folding tables,[2] but from April 2017, the transverse seating was gradually replaced by longitudinal bench seating.[4]

## History

[edit]

The first six-car prototype was built in March 2003, and 15 more sets were subsequently delivered from Hitachi between January and July 2004, entering service on 24 August 2005.[2] Four additional sets (67 to 70) were delivered in 2008 to provide increased capacity. These later sets differ in having a red bodyline stripe added below the windows.[2]

A further three six-car sets were delivered in June and August 2012 to provide additional capacity.[2][5] These three sets, 71 to 73, feature a number of design improvements over earlier sets, including the use of LED interior lighting, increased seat thickness, and opening windows to provide ventilation at the ends of cars.[6]

* Late-build set 72 in May 2023
