In July 1850, construction of the first Neunkirchen station started during the construction of the
Saarbrücken Railway from
Bexbach to
Saarbrücken. On 15 November 1850, the station was opened for freight traffic by the
Palatine Ludwig Railway (
Pfälzische Ludwigsbahn). The first passenger trains ran daily from April 1851 to
Ludwigshafen and back. The station itself was officially opened on 15 or 16 November 1852 together with the Neunkirchen–Saarbrücken line. Eight years later, on 25 May 1860, the double-track Rhine–Nahe Railway (
Rhein-Nahebahn) was completed to a new station building, the so-called
Nahebahnhof ("Nahe station") built in its current location. The old station, dating from 1850, was completely demolished in the process. As early as 7 September 1850, the first coal train ran on the
branch line from Heinitz via Neunkirchen. In 1872, this was followed by the line to the
König ("king") colliery. On 15 October 1879, the single-track line to Wemmetsweiler (now part of the Fischbach Valley Railway), was opened; this line was duplicated in 1891. The station's tracks were remodelled between 1910 and 1922. A new marshalling yard was built in 1912 in the district originally called
Schlawerie (now
Sinnerthal). In December 1914, the underpasses and the five platforms were finished. The outbreak of war on 1 August 1914 delayed the construction of the station building considerably. The building was completed only in 1923; it was regarded as the most beautiful station built by the
Deutsche Reichsbahn railway division of the Saarland. In 1937, daily traffic amounted to more than 3,000 carriages. At the same time it had 17 sidings. On 27 May 1944, the station was severely damaged in an air raid. The station building was severely damaged. Only the right pavilion was largely undamaged. On 21 March 1945 Neunkirchen was taken by American troops. Reconstruction began and rail traffic was resumed. On 31 May 1945, the first scheduled passenger trains ran between Neunkirchen and Türkismühle. Since the line between Saarbrücken and
Homburg (the
Palatine Ludwig Railway) was heavily damaged, the less damaged lines from Saarbrücken to Neunkirchen (the Nahe Valley Railway via
Sulzbach and the Fischbach Valley Railway) was repaired and returned to operations on 25 June 1945. Also re-opened were the Neunkirchen–Homburg line (with Homburg Central Station still closed) and the Nahe Valley Railway from Neunkirchen to
Bad Kreuznach. The badly damaged Neunkirchen station was not rebuilt until the end of 1947. The left wing was rebuilt and the roof was replaced completely. The entrance building and the pavilion, which had previously been separate were now joined by a hipped roof. In the following years only minor architectural changes were made to the exterior and the interior. Otherwise, the building has been preserved in this form until today. The station played a major role because of the heavy industrialisation of Neunkirchen with coal mines and the steel works. In 1955, there were up to 275 passenger train arrivals and departures daily, including four express trains. The number of freight trains was very high. In November 1965, 3 new signal boxes with
relay interlockings went into operation and replaced 10 old signal boxes. The signals from
Bexbach to
Dudweiler are remotely controlled from the signal box
Nof. On 13 May 1966, electric trains began running through Neunkirchen on the line from Wemmetsweiler to Homburg. Freight traffic to Heinitz was abandoned in 1963 and all traffic was abandoned to the König colliery in 1970. ==Platforms==
