Catenary-free Light Rail Systems: Why and How to Choose?

Why implement catenary-free light rail? From minimising visual pollution to a simple lack of space, going catenary-free can help extend networks where catenary light rail may not be suitable. But how do you choose when to go catenary-free?

In this report, discover use cases from around the world and best practices on implementing catenary-free light rail.
