TRACKS

WIRES

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.

g) They do not show up badly
