amsterdam to airport train??

im going to visit amsterdam in may..can someone tell me what time are trains after midnight coz im leaving from amsterdam at 4 in the morning... thanks..i heard that the last train from amsterdam to the airport is at 00 oclock is it true???

Trains run 24/7 to airport.Ask at the station when you get there.(going not coming back).

check with Netherland Embassy in your country and find out.

Trains run roughly once an hour through the night, but not as regular as during the day time.

Mostly the train will leave Centraal station at xx:45, arriving at Schiphol, Amsterdam Airport, 14 minutes later, at xx:59.
The schedule might be different in the weekends!

But do check for the actual day you want to travel, and if in town earlier in the day or week, ask at the station, because in case of work on the track it might interfere with your train and often happens in the night:

Willeke is right, as usual.
You may depart from Amsterdam Centraal to the airport after midnight at 0:02am. 0:30am. 0:45am, 01:45am, 02:45am, and 03:45am and the travel just takes 13/14 minutes.

intil 11 pm
