ご質問ありがとうございます。
少しややこしい文章になってしまいましたが...
"Please take the exit that's located in the opposite direction"＝「逆方向にある出口から出てきて下さい」
"of the one the train you got off is headed to."＝「あなたが下車した電車が向かっていた方向よりも。」
ご参考までに。
When you get off the train, come out of the exit in the opposite direction that the train is going in.
"降りた電車が進む方向と逆側の出口から出てきて"
- When you get off the train, come out of the exit in the opposite direction that the train is going in.
- Once you get off at the station, go to the exit that is in the opposite direction the train is going in.
