SRA Island line replacment review
1. Introduction
Remit
The SRA commissioned a review to advise on options to
continue provision of passenger services on the existing Island Line route
between Ryde Pier Head and Shanklin, beyond the existing Stagecoach franchise
period which has now been extended to 27 September 2003. The brief required
the scoping of two scenarios, 'heavy rail' and 'light rail', in terms of
feasibility of options and the works and equipment investment required, with an
assessment of the costs and scale of any passenger revenue benefits likely to
arise from each option.
The main outputs required from this study include
a strategic review of the existing infrastructure and rolling stock asset
condition, the future peak capacity requirements, and potential infrastructure
and rolling stock specifications and costs for both 'heavy rail' and 'light
rail' scenarios, that would most effectively serve the potential demands for the
Island Line existing corridor, including a high level feasibility and cost /
benefit analysis comparison of 'heavy' versus 'light' rail options over 10, 20
& 30 year horizons.
The review aims to identify and assess
potentially appropriate Development Options to facilitate development of
passenger services along the existing Ryde - Shanklin route. Various resource
levels and investment schemes for train services, rolling stock options: new
electric stock, diesel stock, and light rail, compared with further LUL cascade,
and infrastructure e.g. restoring a passing facility at Brading, were
considered.
We have carried out a separate study, for the Isle of Wight
Council, which considers options for route extension south of Shanklin to
Ventnor, and via the IoW Steam Railway through Smallbrook to Newport and on to
Cowes.
Description of the Island Line
The Island Line
currently extends eight and a half route miles linking the holiday resorts of
Shanklin, the southern terminus since 3rd rail electrification in
1966/67, Lake and Sandown, with a combined resident population of 30,000,
through the village of Brading, and thence through open countryside, past
Smallbrook Interchange (for the Isle of Wight Steam Railway), to the town of
Ryde, also of approximately 30,000 population, terminating at Ryde Pier Head,
the ferry terminal for Portsmouth nearly half a mile from dry land.
Background to the Review
The two year extension of the
existing franchise provides SRA and other stakeholders with the opportunity to
identify and facilitate the best strategic way forward for Island Line. Various
stakeholders have identified the need for investment, e.g. the next heavy
overhauls will be due for the existing rolling stock in 2003/04, and have
suggested scope for modernisation, conversion, and integration with other
passenger services and extension of the system. Some advocate conversion to
'light rail' with the possibility of trams capable of street running. Others
have urged for replacing the railway with bus or guided bus solutions. SRA have
confirmed that such options involving closure of the railway are not on their
agenda for the foreseeable future.
