2. Munich S-Bahn main line, LST planning PT1 for Ibn 2 to 4.2 OiW (VE1039) incl. Laim connecting track of the Sendlinger Spange

The DB Netz AG (Bukr 16) in Germany from Europe region has released this tender for The second S-Bahn trunk line, 5547, will be built roughly parallel to the existing S-Bahn trunk line north of the existing line between Munich-Laim station and Munich East station (Leuchtenbergring junction). The inner-city section begins at Munich-Laim station to the west. East of Munich-Laim station, the double-track, electrified line runs parallel to the existing S-Bahn trunk line for approximately two kilometers on its northern side. The two lines will connect at grade immediately east of Munich-Laim station. Due to the significant changes in the track layout (four platform tracks in the future), the external signaling equipment at Munich-Laim station (equipment of the existing S-Bahn trunk line) will be completely rebuilt. The two outer tracks, 1 and 4, will be controlled by the existing Simis-C interlocking system, and the two inner tracks, 2 and 3, by the new Simis-D interlocking system. Between the two control areas, numerous route adjustments will be necessary due to several track connections. Furthermore, the commissioning of the connecting track of the so-called "Sendlinger Spange" is planned for the transition from construction phase 2 to construction phase 3 of the second S-Bahn trunk line. The planned connecting track is located in the western approach area of ​​Munich-Laim Rbf (marshalling yard) and connects it to the track of the existing S-Bahn trunk line leading towards Pasing. This will combine the Laim Pbf (passenger station) and Laim Rbf (marshalling yard) stations into a single large station, Laim. The scope of this planning service includes the preparation of the PT1 detailed design plans for construction phases 2, 3, 4.1, and 4.2, including adjustments to the LZB (continuous automatic train control) and ZN (signaling system) for the Donnersbergerbrücke (MMDN), Munich-Neuhausen (MNHX), Munich Laim Rbf (MLR), and Munich Pasing Süd (MP) stations. The PT1 detailed design plans for construction phase 1 are currently being prepared and are not part of this tender. The final state of the signaling system (LST) at Laim station was used as the basis for the design planning of the connecting track of the Sendlinger Spange. The pre-approved design document (Sendlinger Spange) serves as the basis for the bid preparation. Upon award of the contract, the approved design document will be made available to the contractor. This, in turn, forms the basis for the contractor to create the PT1 construction phases and the final state of the aforementioned operational points. with tender notice no. 714613-2026 published on 15 Oct 2026.
