Tokyo Metro has implemented an 8-car train formation for the Namboku Line Series 9000, starting commercial operations from December 16.
By augmenting two new cars to the existing 6-car formation, the trains have been upgraded to 8-car formations. Operation has commenced with one trainset, with a gradual rollout to 13 trainsets in the same formation. As a result, the capacity will increase from 882 to 1,200 passengers per train.
Along with the 8-car formation, a major overhaul has been carried out to update the onboard equipment to the same standard as the newest trains. Upgrades include the installation of a derailment detection system that automatically stops the train in case of derailing during major earthquakes, creating free spaces in all cars, implementing security cameras inside the train, and enhancing the performance of the control equipment (VVVF) used to operate the vehicles.
