While electric trolleybuses, trams and railway trains are commonly
refitted several times over their working life (generally accepted to be
30 or so years for a trolleybus), the same can not be said for diesel
buses. Apart from Routemasters, how many diesel buses are there out
there, refitted or not, older than 15 or 20 years?

The Routemaster is only kept in service because of nostalgia and tourist
reasons. Boris the Turk wants to bring them back. The madness of the man -
and they voted for him too.

The fact is, if you look at cities where they operate both diesel and
electric buses in identical conditions, the electric vehicles manage
nearly double the service life of the otherwise identical diesel buses.
