The Brussels S Train, also known as the Brussels Regional Express Network (French: Réseau Express Régional Bruxellois or RER; Dutch; Flemish: Gewestelijk ExpresNet or GEN) is a suburban rail system in and around the Brussels-Capital Region of Belgium. It will offer fast connections and increased frequency within a 30km (20miles) radius of the region, covering a territory inhabited by 2.5 million people.[1]
Most jobs in the Brussels-Capital Region are filled by workers from other regions. Private vehicles clog the city daily, hampering mobility and creating pollution. The RER/GEN is a response to these growing problems. Only 20% of commuters use public transport daily; the goal is to double this figure by facilitating movement into and within the region.
Total costs for the GEN/RER project will be at least €2.173bn.[2] The initially planned nine lines[3] have since increased to 12; but the projected frequency of "a departure at least every 15 minutes"[4] has not been implemented as of early 2018: most services run once per hour, a few twice per hour.
The scope includes widening existing railway lines from double to quadruple; a few additions like the Schuman-Josaphat tunnel; the creation or re-activation of stations just outside Brussels' city centre (Germoir/Mouterij and Arcades/Arcaden on the south-east, Brussels-West and Tour et Taxis/Thurn en Taxis on the west); and the acquisition of new rolling stock.
A first draft of the RER/GEN network was published in 1995. The commissioning of the first lines was then planned for 2002.
Construction requires the approval and funding from the Federal Government and the three regions, as well as the collaboration of four public transit companies (NMBS/SNCB, MIVB/STIB, De Lijn and TEC). The initial work started in 2005, and service was supposed to start in 2012. However, Belgium's administrative complexity caused numerous delays and postponements; the network will now be put into service between 2015 and 2025.[5]
Railway lines within a radius of Brussels are included in the project.[6] Parts of the project are already in place. The most substantial works relate to the quad-tracking of several lines: two tracks for GEN/RER trains, and two tracks for intercity and high-speed trains.[7]
The RER/GEN project includes a double-tracked Schuman-Josaphat tunnel in the north-east of the region. This links the European Quarter to Brussels Airport, cutting to 13 minutes journey times between the two.[4]
Most of the network uses existing rail lines. Increased frequencies and passengers, however, requires other significant infrastructure projects, in addition to the Schuman-Josaphat tunnel:
As of 2020, most services are operated by either new Siemens Desiro or refurbished MS86 "Sprinter", both electric multiple units.
NMBS/SNCB had ordered 305 Siemens Desiro ML single-deck electric multiple units,[8] a €1.425bn contract. These will have a 2MW power rating and a capacity of 280, with construction announced as being at Siemens' plant in Krefeld-Uerdingen,[9] Germany.[4]
