On a recent trip by Tramink, I was struck by the fact that the former
'double arrow' symbol still widely used to identify National Rail stations
does not appear on the trams' relevant destination blinds, eg Elmers End,
Beckenham Junc. and Wimbledon. Here in Belgium, the corresponding symbol
provides a convenient way of emphasising the way road and rail services are
integrated. Is this an example of the 'not invented here' syndrome, or is
there some other simple explanation?
