Two additional tracks were laid for the S-Bahn on the line north to Langenhagen. On this line, Hannover-Herrenhausen station was replaced by the new S-Bahn station at Hannover-Ledeburg. The route was also electrified as far as Bennemühlen and in addition was doubled as far as Bissendorf. Hannover-Langenhagen Airport was connected by a local service for the first time, via the former goods track. From 1995, this line was electrified and extended through a tunnel to the airport's Terminal C, which was then under construction.
