Dear all,

Could you kindly tell me ho to buy it, which kind of ticket is for us. Two people go to Koln from Dusseldorf in one day. I have a international student card. Some guy suggest us to buy a kind of ticket which is return ticket for two people, actually, it can offerd four peoples, but the price is same. the price around 20 Euro. Could you have any detailed suggestion. I really need it.

Your kindly help is really appreciated.

你在杜塞有月票吗，是什么票。有几个人去。把情况搞清楚，再决定买什么票。德国有很多优惠票。

这个周六准备去科隆玩一天，我住在杜塞，准备乘火车过去。大家知道哪种火车票最便宜？

我刚来德国1个多月，现在德文还很烂。在网上查到有3种火车票，ICE， CE，和 RE，RE最慢，但是不能从网上购买。在网上查到的最便宜的价格是10欧每人，单程从杜塞到科隆。

想问问从杜塞到科隆最便宜的火车票是哪种？是不是一定要去火车站买？通过窗口买票是不是要比机器买票贵5欧？我有国际学生卡，买票有优惠吗？

多谢
