On one line which historically extended from Zutphen to Enschede and into Germany, and another line which historically extended from Almelo to Oldenzaal and into Germany. Eventually, the main domestic service operated through Almelo to Enschede, while the line from Zutphen was never electrified. The line through Oldenzaal into Germany is now used by through international trains from Amsterdam to Berlin. One island platform serves all tracks, divided into "a" and "b" sections and with outside access tracks and crossovers at the middle of the platform. Track 2 is the main westbound track and Track 3 is the main eastbound track. The east end of the platform forks into two narrower platforms, between those platforms is Track 11, a stub track.
