NS TRAIN SERVICES AND STATIONS
The capital of Groningen province, in the northeastern part of the country. On what historically was a through line from Harlingen and Leeuwarden, extending east to Nieuweschans and beyond into Germany. Immediately east of the station, a line diverges south to Zwolle. This is the most important line and the only electrified line serving Groningen. Immediately west of the station, a branch line diverges north and east to Delfzijl. At Sauwerd, 11 km north of Groningen, another branch line extends further north and east to Roodeschool. All trains serving Groningen now terminate there. The station is basically set up as a through station, also with "a" and "b" track sections. Except most tracks are stub tracks, and the platforms are all connected with a center concourse. Track 7 is the only through track.
