Memorandum by the Railway Development
Society (RT 07)
INQUIRY INTO LIGHT RAPID TRANSIT SYSTEMS
I refer to your request for memoranda on the
above subject.
The Railway Development Society exists to promote
the use and development of rail transport in all its forms, for
both passenger and freight traffic. We recognise that light rail
(and other forms of transit) have a vital role to play in the
totality of sustainable transport. In the spirit of the Integrated
Transport White Paper, we wish to see as much integration as possible
between all systems.
As a general rule we see LRT systems as offering
the means to bring the benefits of rapid transit to areas not
reached (and not capable of being reached) by conventional rail
(as in Sheffield). It follows that we take a wary view of proposals
to convert existing (or disused) rail routes into light railways
(or busways). Nevertheless we recognise that there can be benefits
to be gained from conversions, in the form of better penetration
of city centres, or linking of otherwise disconnected sections
of rail formation. Most of the existing UK systems (Tyne-Wear,
Manchester, West Midlands, Croydon) illustrate these benefits
to varying degrees.
One major drawback to light rail is that it
cannot cater for freight traffic. Obviously this is not a problem
on unsegregated or partially segregated street-based schemes.
But when existing rail formations are utilised, there is a danger
that rail freight flows may be sacrificed. Compromise solutions,
such as parallel single-track working, or moving freight at night,
limit capacity and produce operating problems. Willingness to
lift restrictions on mixed operation of light and heavy passenger
services in the UK at long last (for the Sunderland metro extension)
is welcome. Such shared working has been routine in Karlsruhe
for many years without mishap, and the scope thus created for
through running greatly increases the value of the light rail
system. Perhaps in due course the same flexibility will be extended
to include freight. Meantime, where rail formations are used,
care must be taken to ensure that existing rail freight traffic
is not displaced, and that the track and structure gauge required
for conventional rail operation is safeguarded to allow for future
upgrading or through working.
Where conversions do take place, or where LRT
links otherwise unconnected parts of the heavy rail network, it
is essential as we see it, to ensure that the benefits of integration
with the "mainline" rail network are retained, including
through fares and ticketing, information availability out of area,
and so on. Ideally we would wish to see this extended to all LRT
systems (zonal fares systems in the conurbations concerned, and
computerised journey planners, will facilitate this). But in the
meantime any converted route must remain just as much part of
the railway network as any other franchised service. Equally,
LRT has to be fully integrated with the bus system. Where this
has not been done, and premium fares charged, this had tended
to result in lower patronage and financial problems.
Much has been made in several quarters including
the government, of the high cost of light rail/LRT in comparison
to investment in buses. Yes of course, any fixed track system
is relatively expensive, and is only appropriate in locations
where patronage will merit it, but it is misleading simply to
compare the cost of trams, say, with that of buses. It is widely
recognised that the higher quality the transit system, the more
people are prepared to forsake private cars for public transport,
and experience in Continental Europe bears this out. In general,
trains and trams perform best, followed by guided buses or trolleybuses,
with ordinary buses least successful. The question to ask is not
"how many buses can be bought for the price of an LRT system?"
but rather "how many car journeys are prevented per pound
spent on each type of transit system?"
Account also needs to be taken of the environmental
benefits, especially in polluted city centres, of electrically
powered transit systems, whether tram, trolleybus or electric
rail, compared to diesel trains and buses or petrol driven cars.
The present management and financial structures, especially of
the rail industry make this difficult.
Finally, we note that LRT and tram systems are
widespread in European and North American cities. Many different
types of system have proven track records in different circumstances
appropriate to their several characteristics. By contrast in the
UK, all such systems seem to be regarded as unproven new technology,
to be treated with kid gloves and installed warily in only one
location at a time! This is misguided, frustrating, and contrary
to the spirit of the Integrated Transport White Paper.
