Toei 10-300R Series Train on Keio Sagamihara Line Running toward Nagayama Station 4

10-000 series part has many features that cannot see on recent trains: diamond-shaped pantograph, non-UV-shield-type windows, surface with waves. One exception is the centralized air conditioning unit on the roof. That kind of air conditioner was developed for underground trains first, then, introduced to most trains.
