Note that there are Metro/Subway/Underground/Rapid transit railways that have tunnels that would be placed high on this list. The longest such tunnel is the Serpukhovsko-Timiryazevskaya Line of the Moscow Metro, 41.5 km (25.7 mi) long. Often they are not considered continuous because the stations do not count as tunnels. See also List of further tunnels by length.
