ここは東京都葛飾区...京成立石駅の踏切横断中に気が付いたのですが…
This place is located in Katsushika-ku, Tokyo ... I noticed it while I crossed the level crossing of Keisei Station stone ...
「立石停車？」！？
"Tateishi stopping?"! What?
運転手さんへのメッセージにしては…この駅に停車するのは「各駅停車」のみなのです。
As a message to the driver of the train ... It is only "a train at a local train station" to stop at this station.
...謎過ぎ。
...This signboard is a mystery.
