Greater London Light Rail Under Construction — Active LRT Extensions and New Route Builds

Greater London light rail lines currently under construction. Active LRT extensions, new route builds and stop additions across the network.

Greater London light rail and LRT lines currently under active construction: first-line systems in cities building their initial LRT network, extensions serving new development areas and upgrades converting street tram lines to segregated light rail operation. Light rail is frequently chosen over full metro for medium-demand corridors where surface or at-grade construction is more cost-effective than tunnelling.

Greater London currently has 116 railway segments under construction including 90 railway and 26 light rail.
