想买London bridge to brighton的火车票，界面显示super off-peak day retum 最便宜，但选了它，显示
Your ticket is from London Thameslink to Brighton
[size=1.4]Stations included within London Thameslink for your ticket:- Elephant & Castle
- Farringdon
- London Blackfriars
- City Thameslink
Route: Not valid for travel on London Underground services.
意思是我可以从上述四个火车站取票，坐火车去布莱顿吗？
网上其他地方也没有讲清楚，故来求助，望解答。谢谢！ |
