Arrivals to Schiphol (airport and train station).
During your wait for your luggage it is already possible to buy a paper OV-chipcard to Ede-Wageningen using the ticket vending machines. You can also choose to buy an anonymous ov-chipcard already.
Note that the paper OV-card machines and the ticket offices generally do not accept credit cards. You can pay with debit cards (Maestro). Paying in cash is only possible at the ticket office (in the main hall near the platforms). It will cost you an additional 50 eurocents.
The tickets are valid on all national trains and some international trains. For national trips like this, no reservation is needed. With the ticket you can just enter the first train that goes into the desired direction.
After having left arrivals, just follow the signs with the trains on it towards the center hall.
From Schiphol Airport to Ede-Wageningen
Now with your OV-chipcard in hand (see above) you can go find the right train. The large blue screens show you how to reach all larger train stations (including Ede-Wageningen) and where your train leaves from. The yellow signs also indicate departures of trains and are sorted on destionation first. If you are not sure what to do, or where to go, don't hesitate to ask the NS service staff for help. Before you head down to the platform don't forget to check in, the check in/check out poles are close the the escalators in Schiphol. Simply hold your card in front of it until it bleeps and shows a green light. (When you get off check out again by doing the same thing, you can also see you credit now!)
To get to Wageningen the fastest, you want to get an Intercity service heading for Nijmegen and that stops at Ede-Wageningen, this is where you have to get off!
From Ede-Wageningen to Wageningen Bus station
At Ede-Wageningen train station there are several lines that go to Wageningen city center (bus station); bus 84, 86 and 88. Depending on you destination one is most suitable for you. Bus 84 and 88 have pretty similar routes, but line 84 goes over the WUR campus (no stop at Hoevestein). Bus 86 goes via Bennekom and through Wageningen city center. If you are staying in an Idealis flat or have to go to their office for your room take line 84 or 88. If you have to go the university (Forum building) take line 84.
How to find the bus? When you walk down the stairs from the train platform go to your right. Walk up the stairs again (or take the slopes on the left if you have a lot of luggage) and you will see the bus platforms slightly to your right.
Remember the OV-chipcard you just bought at the airport (not the paper one)? You can use this card here as well to enter and pay for the busses (check in when you enter, check out when you leave).
