The Nyon train station was recently updated with a fresh coat of paint, a Post Finance Bank Machine, and a new larger quick mart. However, the bathrooms haven't been replaced and are still in the form of honey buckets. The train station is a small one, but usually has two people in the ticket area to help with any questions. There is only one ticket machine that usually has a very long line on the 2nd platform. There is a small bar/cafe also in the train station, which I haven't ever tried.
Note: it is confusing and I often get tourist questions on how to find the train to St. Cergue. To get to the train that goes to St Cergue you need to cross under the train station to the other side, and then take a right and down the stairs to buy tickets and get on the little red train.
Just a simple train station nothing fancy like the larger cities of Lausanne or Geneva.
TIP: you can find bike rakes also under the train station on the other side. There are luggage lockers outside the train station to the right of the entrance across from the entrance to the larger Apero mini market. Near the post finance machine. read more
