When it comes to buses breaking down, it is important that you compare them to similar occurrences in streetcars (
For example when a bus broke down in the Seattle Transit Tunnel it took a half an hour to extricate it, whereas it took 3 hours and forty minutes to do the same for a streetcar (
LRT) - ironically it was towed out by a bus.
The frequency of breakdowns in high capacity buses is equal to that occurring in streetcars (
LRT) according to the American Public Transit Association.
In such emergencies, if the down time is prolonged, buses can relocate on the surface. Disabled rail vehicles shut down the whole system. The death and serious injury statistics of
LRT are so much higher than buses. The City of Denver is faced with over a billion dollars in extra expenditures to guarantee a so-called “fail-safe” software computer system designed to prevent one street car running into another even though they are using drivers. Yet, another enormous expense for which no finances have been budgeted.
