Rail transport in Spain
Rail transport in Spain operates on four rail gauges and services are operated by a variety of private and public operators. The total route length in 2004 was 14,781 km (8,791 km electrified):
Most railways are operated by RENFE; metre and narrow-gauge lines are operated by FEVE and other carriers in individual autonomous communities. It is proposed and planned to build or convert more lines to standard gauge, including some dual gauging of broad-gauge lines, especially where these lines link to France, including platforms to be heightened.
