WHY PUBLIC TRANSPORT?
There is a need for public transport to and from the Western Riverside. The site must be linked to all of Bath and to the surrounding and national transport system.
Deliveries and some personal journeys will have to be undertaken by road, the site will need provision for this.
Many personal journeys could be made by public transport, thus reducing the necessity for land-wasting roads and car parks. A good quality public transport system would not only give the benefits of reduced car usage, but would enhance the value of the site in many other ways.
WHY TRAMS?
The current public transport systems in Bath
have become the transport of last resort and would not be acceptable
to many people using the site.
Some of the features of a public transport system which might
help to make it a viable alternative to the motor car could be
provided by bus, but attempts to do so have proven uneconomical
in both the short and long term. The tram has a proven record
of attracting motorists away from their cars without the need
for operating subsidies.
A tramway represents a long-term investment in the infrastructure of an area, it is the perceived permanence and long-term reliability of this which enhances the value of land and property, and encourages regeneration.
WHY A NETWORK?
There are few obvious corridors of movement in the Bath area that are amenable to public transport development. The traffic that regularly jams certain major routes will not be removed by a point-to-point public transport corridor. This is because residential, retail and employment areas are geographically scattered and complex journey patterns are the norm in Bath. A mixed development on the Western Riverside site is also expected to fit in with this pattern.
The public transport system must be directly accessible to as many residents and visitors as possible - if a car journey is needed for access, public transport will have failed in its purpose. A network of routes is the only way of achieving success in Bath.
The facilities for interchange between routes
are of particular importance, this must be made easy so that a
'seamless' journey results. With the proposed tram system. no
more than one straightforward interchange between routes will
be necessary during any journey.
Interchange arrangements
CORRIDOR WIDTH
A double-track tramway will fit easily into an alignment 9 metres wide and this can be shared with other modes under appropriate circumstances. At 'pinch-points', a width of 3 metres is sufficient for a single track section, provided there are passing loops within a sensible distance each side.
STOPS AND ACCESS
Tram stops require a ramped section of pavement
about 300mm above the track level and the alignment needs to be
widened by about 2m each side to accommodate the waiting area.
Where space is restricted, stops do not need to be placed in pairs
opposite each other, they can be staggered or a single central
waiting area can be used.
More on stopping arrangements
Experience shows that intending passengers prefer a direct route onto the tramstop. If this is not provided, there will be continual problems from people taking short-cuts and breaking down any fences and barriers.
Tram stops can be located inside buildings.
This is particularly desirable at large interchanges, in prestige
developments which intend to promote the use of public transport
and at hospitals where frail patients must be protected from the
weather.

TRACK AND EQUIPMENT
Tram tracks are usually rolled steel grooved-girder
rail, set in resilient mastic in a concrete base. The strength
of the supporting structure will depend on the maximum vehicle
weight - in the case of the TfB proposals around 20 tonnes fully
laden. This will be spread over 4 axles with 8 wheels; and further
spread by the rails themselves. Dynamic loading needs to
be considered, but nowadays the resilient mastic reduces the heavy
rumbling shocks which were so characteristic of older trams .
More on rails
Tramways are designed so that the alignment can be safely shared with other transport and pedestrians. The 'swept path' of the tram is marked out (often with a different coloured paving) to bring it to the attention of other road users.
Cycle paths are a special case and whenever
possible should be segregated from tram tracks. The currently
proposed longitudinal cycle path through the Western Riverside
is alongside the river, remote from the proposed tramway alignment,
and will not need any special consideration.

Overhead wires are not as unsightly as may
be supposed. In some large industrial towns the supporting structures
have been criticised for poor æsthetic design, but the criteria
for good design are well known and should be applied early in
the planning process. Elegant tramway poles are used as a feature
of an attractive street environment in some towns.
More on the appearance of the wires
Communications and power ducts alongside the track are essential for the tramway's own puposes and sometime extra duct space can be provided for other services needing to follow a similar route. A tramway could be beneficial in the provision of a communications 'spine' for the site.
CROSSING PLACES
There are a number of places on the Western Riverside site where north-south routes might intersect the tramway. At present there is a disused railway embankment along the proposed alignment and a number of bridge abutments remain at these road-crossing points.
A tramway can cross lightly-trafficked routes, such as these, 'at grade' without the need for bridges or other structures; so the embankment could be removed or used for some other purpose without any detrimental consequences for the tramway. The major intersections all coincide with desirable stopping places for the tram, so speeds at these points will be low and no special safety precautions would be needed.
It is important for cycling safety that any
possible cycle intersections are set at right angles to the track.

SERVICES AND REPAIR
Contractors' plant such as gas, water or electricity mains should not be located beneath the tramway in such a position that acess or repair of the plant would necessitate closure of the tramway. During construction, suitable ducts or 'bridges' should be incorporated to allow replacement of fauly plant where this is unavoidably located underneath the alignment.
DEPÔT
A depöt will be required for the tramway.
This could usefully be located on the Western Riverside site in
an industrial area.

ACCESS and INTERCHANGE
The proposed tramway is a single route through
the site in an east-west direction. Only two points of access
are required. At the western end of the site, access is required
into Windsor Bridge Road where two local routes will diverge to
the north and the south. At the eastern end of the site, the existing
Green Park Station approach ramp is adequate to carry the services
into James Street West and into the City Centre Circle.
Proposed routes off site
During the initial phases of a tramway, it
is sensible to relocate or curtail some bus services so as to
feed into the existing tramway routes pending completion of the
network. A suitable location for a transport interchange should
be identified at the western end of the site. The existing bus
stops in the city centre will serve the eastern end.

2 | Proposed tramway routes | Tram routes diverge to north and south, serving residential areas and hospital. |
3 | 'Gasworks Square' | Public transport interchange during early phase, to integrate with local buses |
4 | Midland Road crossing | Crossing at grade. Tramstop desirable in this area will automatically slow trams for safe crossing. Can be further north if required depending on land use |
5 | Victoria Bridge Road crossing | As above, except: Tramstop needs to be near southern site boundary to serve hotel in Brougham Hayes |
