Operations

The 2000 series sets are used on the Tokyu Oimachi Line and Tokyu Den-en-toshi Line and Tokyo Metro Hanzomon Line inter-running services; they 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.[2]

Design

Based on the earlier Tokyu 9000 series EMU design, two sets were introduced in 1992, followed by a third in 1993.[2] 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.[2] All three sets have since been modified with full-colour LED destination indicators.[2]
