Otxarkoaga is a station on line 3 of the Bilbao metro.

The station is also served by Euskotren Trena commuter and regional rail services.

The station is located in the neighborhood of Otxarkoaga, part of the Otxarkoaga-Txurdinaga district of Bilbao.

Txurdinaga follows the same cavern-like station layout shared by most underground stations of the system, designed by Norman Foster, with the main hall located suspended directly above the tracks.

[2] Unlike the two other lines of the Bilbao metro system (which are operated by Metro Bilbao S.A.), line 3 is operated by Euskotren, which runs it as part of the Euskotren Trena network.
