The service level would be decided by the tramway
operator, who would take into account such factors as passenger
loadings and time of day. .
It is possible to gain some idea of the potential service from
rough calculations using available data.
The total track length of the proposed Bath system is 40 km
If 40 trams were used, this would give, on
average, 1 tram per km
Half of these trams would be inbound and half outbound so travelling
in a given direction, the trams would be spaced at 2 km intervals
on average.
A reasonable average service speed for a modern
tram in Bath would be 20 kph
(Wolverhampton quotes 35kph but
has a large proportion of reserved track)
This would give 10 trams per hour past a given
point in one direction or a 6 minute service.
This would be the maximum theoretically attainable
A 7.5 minute service should be possible in practice on many routes
and where two routes shared track, such as the Western
Riverside, a 3.75 minute service would result..
