In preparation for the next day's operation, two model 800 cars, which had departed from Hamaotsu Station at 10:05 and an hour later were deadheaded to Shinomiya Station using 600V direct-current wiring and the scene where model 800 cars, which were old-model cars, and model 600/700 cars, which were new-model cars, passed each other was seen in the vicinity of Kamisakaemachi and Oiwake.
浜大津10時5分発とその1時間後にもう1本800系が翌日の営業に備えて直流600Vの架線の下を四宮まで回送され、上栄町・追分付近では、京津線での600・700形との新旧擦れ違いが見ることができた。
