6. Conclusions
6.1 Summary of results
This study has evaluated the likely
feasibility and economic case of options for railways on the Isle of Wight,
principally the routes from Ryde to Shanklin and thence to Ventnor and from Ryde
to Newport via Smallbrook Junction and Havenstreet, with a possible extension to
Cowes. An initial appraisal identified three options as being of sufficient
potential to carry forward to a more detail evaluation:
Option 1: Ryde
to Shanklin extension to Ventnor
Reinstatement of the railway between
Shanklin and Ventnor, operating a half-hourly service as an extension of the
current Ryde-Shanklin railway using cascaded LUL tube rolling stock and with
3rd rail electrification.
This option provides ample economic
benefits to cover operating costs. According to standard SRA planning criteria
these are insufficient to cover the substantial initial infrastructure outlays
(cost benefit ratio of 0.92). There may be disruption disbenefits and risks
relating to this option, principally concerning water supplies currently using
the tunnel at Ventnor and the need to remove light industrial units occupying
the track bed at both Ventnor and Wroxall.
Option 2: Ryde to
Newport
Reinstatement of the railway between Wooton and Newport
(Barton), upgrading of the IoW Steam Railway between Smallbrook Junction and
Wooton for 55 mph line speed with shared operation. An hourly service would
operate between Ryde and Newport using purpose built diesel multiple unit stock.
The scope and case for a more frequent service in peak hours, would be
considered at more detailed feasibility stage. 'Heavy rail' is selected to
ensure compatibility with existing heritage rolling stock in terms of safety
case.
This option provides good value for money according to standard SRA
planning criteria (cost benefit ratio of 1.23). We consider that this option
may be progressed further and could be appropriate for SRA Rail Passenger
Partnership funding. A spin-off benefit not quantified would be the potential
for the IoW Steam Railway to operate into the Newport terminus.
Option 3: Ryde to Newport to Cowes
Provision of Option 2
together with an extension using street running through Newport to Cowes to
operate an hourly service from Ryde to Cowes using purpose built diesel
trams.
Although this option provides substantial economic benefits these
are insufficient to cover the very substantial initial infrastructure outlays
(cost benefit ratio of 0.8). The very substantial encroachment on the former
track formation means that street running is required in both Newport and Cowes,
with very limited potential for segregation from road traffic. We conclude that
this option offers little benefit to the passenger compared with road based
public transport and may have a negative impact on road congestion at some
locations.
6.2 Recommendations
We advocate that the
following approach be adopted by the Council:
6.2.1 Ryde to
Newport
The Ryde to Newport route (Option 2) be developed to more
detailed full-feasibility stage: to further refine the specification, capital
costs, and demand forecasts.
6.2.2 Extension to
Ventnor
As the extension of Ryde - Shanklin line to Ventnor (Option
1) provides a slightly negative economic case in purely transport terms, the
Council may wish to consider whether additional benefits relating to
regeneration of Ventnor or social accessibility for its residents may be
applicable.
If this scheme is to be developed further then the
feasibility of removing the water supply from the tunnel and the impacts of the
relocation of industrial units should be investigated.
6.2.3 Cowes
extension
Extension beyond Newport to Cowes (Option 3) offers a
relatively weak economic case and doubtful advantage over road based public
transport. We conclude that developing a rail service for the Cowes - Newport
corridor should not be viewed as a high priority.
6.2.4 Next
steps
We recommend that the study findings be discussed
with:
- the Strategic Rail Authority to consider how best the emerging worthwhile
options may be progressed. In addition the SRA will then be able to establish
goodness of fit with their emerging strategy for Island Line.
- the Isle of Wight Steam Railway to further establish the scope for shared
running access onto their infrastructure.
We suggest that the
possibility of connecting rail / bus links, with through ticketing, should be
investigated as a potential interim improvement in accessibility: a likely
priority for this could be Shanklin station to Ventnor.
