Does anyone know how much time it take on train from Cologne to Amsterdam? Also how much $?
Using the German Rail website, you will find the most expensive trains, ICEs, do the trip in 2h38m, direct, for about €57 pP. By purchasing ahead you can get a date and train specific, non-refundable fare for the same trains as low as €19.
For a little less, €41, you can do the trip, without ICEs, in 4 hours with 3 or 4 changes of trains.
Those tickets are sold in Euro, not dollers. A Euro currently costs about $1.30. To get the exact current conversion, see www.oanda.com.
2.;5 to 4.5hrs depending on the train you take.
