Tokyo Monorail 10000 series

The Tokyo Monorail 10000 series (東京モノレール10000形) is a monorail electric multiple unit (EMU) train type operated by the Tokyo Monorail on the Tokyo Monorail Haneda Airport Line in Japan since July 2014.

Design
The body design is based on the earlier 2000 series trains first built in 1997, and uses friction stir welded (FSW) aluminum alloy panels.

Formation
, the fleet consists of seven six-car sets, numbered 10011 to 10071, and formed as shown below, with four motored ("M") cars and two non-powered trailer ("T") cars. Car 1 is at the Hamamatsucho end.


 * "x" stands for the set number.
 * Cars 1 and 6 each have a wheelchair space.

Interior
Passenger accommodation consists of a mixture of facing 4-seat bays and longitudinal bench seating, and includes baggage racks next to the doorways. The seats are covered in a blue moquette incorporating the traditional Japanese seigaiha (青海波) pattern. LED lighting is used throughout. Passenger information is provided by 7-inch wide LCD displays above the doorways. Information is provided in four languages: Japanese, English, Chinese, and Korean. Initially one screen is provided above each doorway, but provision is made for installing a second screen in the future.

History
This vehicle was introduced to replace the aging 1000 series.

The first set, 10011, was delivered to Tokyo Monorail's Showajima Depot in March 2014. It entered revenue service on 18 July 2014.

Structural damage
On 31 May 2022, structural cracks were discovered on seven 10000 series trainsets, causing a reduction in peak-hour service from every four minutes to every five minutes. The cracks were mainly found on an aluminum part which connects the body of the vehicle to the bogie.
