Light rail in 1970: Light rail milestone 6

Scores compare light rail with the other types on speed, efficiency, accessibility, safety, cultural impact and tech disruption. They are relative editorial judgements, not laboratory ratings. Seven chapters dig in: origins, systems and cutaways, how it works, cultural life, legendary icons, what comes next, and how money and regions structure the fleet.

Light rail is not a single machine — it is a family of designs, duties and cultures inside the rail atlas. This deep intro maps how the type varies, what systems make it work, and why places adopt it differently. Street-running LRT, exclusive right-of-way and subway-surface hybrids sit between tram and metro.

High-floor vs low-floor fleets split accessibility strategies. Priority signalling, level boarding, catenary/battery segments and crashworthiness standards set performance. Grade-crossing protection is a core safety system on shared corridors. New LRT lines become mayoral legacy projects — celebrated or contested block by block.
