Ola is a railway station in Sondika, Basque Country, Spain.

Due to budget constraints, the original alignment through Mount Artxanda included prolonged steep slopes.

This caused a serious accident only two months after the opening, after which the decision was taken to build a tunnel directly under the mountain.

As a result, the only service calling at the station from November 2015 to April 2017 was a shuttle to and from Sondika.
