The station is located in the network of the Saarländischer Verkehrsverbund (Saarland transport association, saarVV).

Sulzbach (Saar) station was opened with the commissioning of the Neunkirchen–Saarbrücken section in 1852 as a continuation of the Palatine Ludwig Railway (Pfälzische Ludwigsbahn) between Ludwigshafen and Bexbach, which had been completed in 1849 and extended to Neunkirchen in 1850.

An interlocking that controls signalling in Sulzbach and Friedrichsthal stations is located next to the track at the level of the platform, but this is remotely-controlled from Neunkirchen in regular operation.

Passenger services are operated over the first two tracks (next to the station building) and stop at a covered island platform.

The RE trains of line 3 to Mainz, operated since the takeover by vlexx, have not stopped in Sulzbach since the timetable change of December 2015.
