Tram is one of the most environmentally friendly means of transportation in Hong Kong.
Hong Kong Tramways has been committed to reduce noise pollution to a minimum by introducing the thermit welding technology. The seamless rail welding greatly reduces noise when compared to the fishplate rail joint adopted before. In our 30-kilometer track system, more than 20 kilometers are newly-constructed tracks connected through thermit welding process. The rest of the tracks will be replaced in phases.
Hong Kong Tramways also carries out a regular maintenance program to replace all worn traction gears and resilient wheel rubber of the tramcars with the objective of reducing running noise.
