Operations

The 2000 series sets are used on Tokyu Den-en-toshi Line, Tokyu Oimachi Line, and Tokyo Metro Hanzomon Line inter-running services, but are not capable of running through onto the Tobu Skytree Line, and have circular "K" stickers on the centre front cab window to indicate this.[1]

Design

Based on the earlier Tokyu 9000 series EMU design, two sets were introduced in 1992, followed by a third in 1993.[1] The first two sets were delivered with roller blind destination indicators, whereas the third set was delivered from new with 3-colour LED destination indicators.[1] All three sets have since been modified with full-colour LED destination indicators.[1]
