REGARDING the Sandilands tram derailment, why is it that Britain’s modern tram networks do not follow British custom and display speed limits in mph? Speed limit signs in kph display a higher figure, giving passengers in a speeding tram a false sense of security. Was this obvious problem not considered by the RAIB (Rail Accident Investigation Branch)?
Mixing measuring systems is never a good idea. In Britain, speeds are thought of in mph and newspaper reports of the Sandilands crash converted the speed limits into mph.
