It has, however, had less of an impact on other centres such as Wimbledon
but it has not led to the downturn of smaller centres which was a concern when
the system was being planned and built.
To maximise the benefits of future systems, besides ensuring that it offers a
high quality transport service and integrates to other transport systems, the areas
to be served need to ensure that:
• They use the goodwill and feel good factors generated by new light rail/tram
schemes to aggressively market their areas;
• Training schemes are put in place to enable residents to take up the
employment opportunities that become available to them through improved
• The system is highly visible and associated stops are of a high quality; and
• Planning policies facilitate appropriate residential and commercial
developments around tram stops.
