Key facts

Tramlink is much less intrusive than conventional railways as it does not need wide sections of segregated track. Trams can climb steeper gradients and handle tighter curves, thereby fitting in around existing buildings and spaces. Long stretches of the routes use converted railway tracks which are no longer in use, minimising visual and noise impact.

Noise impact

One of the outstanding features of Tramlink is the quiet and smooth running of the trams. Powered by electricity wires overhead, modern trams generate none of the engine noise of cars, lorries or other road vehicles. In fact Tramlink has been designed with sound reduction in mind. In order to minimise noise, wheels are lubricated to reduce squeaking and track is continuously welded and mainly set in ballast. At depot, all practical steps have been taken in accordance with the 1990 Environmental Pollution Act.

Air quality

Existing modes of transport are significant sources of air pollution. Exhaust fumes are thought to cause harm to health, particularly to those already suffering from respiratory illnesses. Motor vehicle gases also contribute to global warming - about half the current warming effect is due to carbon dioxide (CO2). The Croydon Environment Audit 1995 estimated that nearly 880,000 tonnes of CO2 are emitted by vehicles in the Croydon area every year. Although the generation of electricity needed to run trams has the potential to create air pollution from the power station, this is subject to strict government controls and trams do not emit fumes or pollutants.

Flora and fauna

In building the Tramlink system, we have kept to a minimum the need to disrupt wildlife. Where trees absolutely had to be removed then replacement planting form part of the landscaping works. When this landscaping is complete there will be more trees in the area than there were prior to construction. Croydon Council has responsibility for landscaping, for which it has set aside a million pounds, and is undertaking a comprehensive programme of replanting which ensures high standards are met.

Soil and archaeological surveys

Any soil brought into the Addington Hills area is similar to existing soil to ensure that 'alien' material is not imported. The opportunity is being taken to re-establish areas of heather which have been smothered by recent tree growth.

Wessex Archaeology carried out an Archaeological Impact Study to identify and protect all known or suspected remains along the routes - archaeological investigations took place during construction in certain areas.

Badgers

Discussions were held with wildlife groups and the Joseph Firbank Society on the most appropriate ways of protecting badgers living along the route. Badger tunnels and badger proof fences will ensure that badgers cross safely and with ease.

Open space for Croydon

Croydon Council has established two new open spaces to replace land used by Tramlink:

Stroud Green Well in Shirley. This five acre site was once a playing field but had become overgrown. It has now been cleared and opened to the public.

Threehalfpenny Wood. Six acres previously known as Addington Soakage Field has been transformed and opened to the public.
