Design
The 7700 series cars are rebuilt from former 7000 series cars, which themselves were rebuilt in 1977 from cars dating from the 1950s with new bodies on the original underframes.[2] The 7700 series cars reuse the bodies and air-conditioning equipment of the 7000 series cars but with new bogies identical to those used on the 8900 series cars and VVVF control equipment.[3] The interiors have also been completely refurbished with the doorways widened from 900 mm (35.4 in) to 1,000 mm (39.4 in).[1] Interior LED lighting is used.[1] The cost of building the 7700 series from the earlier 7000 series cars is approximately 130 million yen per car, compared to the cost of approximately 180 million yen for purchasing new 8900 series cars.[4]
