Infrastructure
In 2003, the network constituted 3,518 km of railways, all of which were standard gauge: 1,435 mm (4 ft 8 1⁄2 in) gauge. Of all of those railways, 2,631 km were also electrified. Most electrified Belgian lines use a 3,000 volt d.c. overhead power supply, but the high speed-lines are electrified at 25,000 volt a.c., as are recent electrifications in the south of the country (Rivage - Gouvy and Dinant - Athus lines).
Trains in Belgium normally run on the left hand track. This is in contrast to road vehicles, which drive on the right hand side of the road and is evidence of the British involvement in building the rail network in the 19th century.
The railway network is controlled and maintained by Infrabel, a subsidiary of SNCB Holding.
