Nearly all the trains, including three-door cars in the afternoon or later, are operated with cross-seat cars, but when the trains of Series 9000 are in the periodical inspection or parts change, the cars furnished with long seats are sometimes used instead, even in the afternoon or later.
おおむね正午以降は3ドア車も含めてクロスシート車での運用に統一されるが、9000系が検査や部品交換の時期に入ると、午後以降にも一部の便でロングシート車による代走が行われることがある。
