关于火车票off peak open return的问题想请问各位帅哥美女求教：我买的从london kings cross到Cambridge station的off peak open return的火车票，我想问问等我返程的时候是不是也必须只能回到london kings cross站？我能在london liverpool street站下车么？
It depends. If the ticket says 'any permitted' then you can travel to Liverpool Street as well. Only KingX and Liverpool street have direct trains to Cambridge.
