Public transport based on tracks has many advantages over
other types:
a) The track represents an irreversible investment
in local transport infrastructure and becomes a positive factor in
long-term land use planning. Tramways are in a similar class to
railways in this respect
b) The balance of high infrastructure costs and
low running costs favours long operating hours and as fast and
frequent a service as possible.
c) A predictable rail-guided path gives safe
operation in pedestrian areas and gap-free level boarding at stops.
It also allows tramways to go through very narrow gaps between
buildings, which would be unsafe with steered vehicles.
d) Rail guidance leaves virtually no gap at a
level loading patform, making access easy for all users.
e) The smooth running surface allows a high
proportion of standing passengers in safety, which maximises profits
during peak times.
f) The visible rails give a clear indication of
the tram route and inspire confidence that a tram will arrive soon
and at the right place.
g) The track layout must be planned to avoid
traffic jams and thus results in a more reliable service.
h) In poor weather, rail guidance allows safe
operation and keeps a tram on its allotted course.
i) Breakdowns or crewing problems must be resolved
promptly. This imposes a discipline on the operating company, it
gives the staff a pride in their work and the passengers confidence
in staff loyalty.
Overhead wires are used
because:
a) They remove pollution from cities by
allowing electricity to be used to power vehicles
b) They are the safest and most reliable way to
convey electricity to a moving vehicle.
c) They are the cheapest and most efficient way to
convey electricity to the vehicle.
d) They have a long life and low environmental
remanufacturing costs.
e) The current collection apparatus does not add
substantially to the weight of the vehicle.
f) They can be installed on routes where there are
under-road cellars because they do not need apparatus to be buried in
the road surface.
