Design
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
As of 1 April 2016, 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]

History
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 2008.[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][3] 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.[4]
From April 2017, the transverse seating in cars 3 and 4 was gradually replaced by longitudinal bench seating.[5]
