The Atkins Report on alternative rail upgrades has been published on
the
DfT» website:
http://www.dft.gov.uk/pgr/rail/pi/highspeedrail/alternativestudy/ These are summarised in the Strategic Outline Case (see pages 73 -76
plus Annex A page 77 and options copied below) and covered in more
detail in the Rail Interventions Report:
'8.1.1 The Packages
The rail strategic alternatives to the High Speed 2 proposition
started from the point that the West Coast Main Line and the other
rail routes to the West Midlands and the North West are at full
capacity, and that no extra services can be run without any additional
infrastructure investment. The timetable has been optimised.
A total of five rail packages were identified as Strategic
Alternatives to the High Speed 2 proposition. The first of these,
train lengthening, was not taken forward for further analysis as it
was not likely to be considered as a viable alternative to High Speed
2, since it made no impact on journey times.
The remaining four packages were largely incremental, with each
subsequent package building upon the preceding one.
8.1.2 Package 2
Package 2 and 2A show that with extra infrastructure investment (in
the region of ^3.6 billion) the capacity of the
WCML▸ can be enhanced
significantly. Subject to further engineering and capacity modelling,
it should be possible to operate an extra four or five trains per hour
(
tph▸ ) in a standard off-peak hour, resulting in a total of 15/16 tph
into/out of Euston.
This package has a reasonable impact on journey times. Journey times
to Manchester are forecast to decrease by 6.5 minutes, to give an
average journey time of approximately 121.5 minutes. Journey times to
Birmingham are also forecast to decrease by approximately 12 minutes,
to give an average journey time of 73 minutes ^ primarily as a result
of serving fewer intermediate stations.
Depending on the assumptions made in relation to rolling stock
procurement and timetabling contingency to assist recovery from delays
and incidents, this package has an indicative
BCR▸ of between 3.63 and
2.19. This BCR may change should the forecast scheme costs and
benefits be developed in greater detail, as part of the project
development and value engineering process.
Whilst Package 2 does impact moderately on the environment at various
locations, there are not predicted to be any very significant adverse
impacts with this package, and it is the least environmentally
damaging of the packages. This is mainly due to the fact that it does
not have any new infrastructure build on the Chiltern Lines, so does
not impact on the Chilterns Area of Outstanding Natural Beauty (
AONB▸ ).
The proposed works will be disruptive to passengers. The extent of
this depends on the scheme design and the scope of staging works, and
has not been assessed in detail at this stage.
8.1.3 Package 3
With significant investment on the Chiltern Line, in addition to the
WCML investment in Package 2, it should be possible to operate the 3
trains per hour (previously WCML) London to West Midlands services on
the Chiltern route. The infrastructure works for this package are
forecast to cost in the region of ^12.5 billion, and will free up to
three London to North West paths on the WCML.
Although the investment will electrify the Chiltern route, and have
other benefits, it will not significantly further reduce journey times
between London and the West Midlands/North West. Typical journey times
to Manchester are forecast to remain at around the 121.5 minutes
achieved
by Package 2, with times to Birmingham decreasing further to give a
typical non ^ stop journey time of around 70.5 minutes to Moor Street
station.
Depending on the assumptions made in relation to rolling stock
procurement this package has an indicative BCR of between 1.24 and
1.11. This BCR may change should the forecast scheme costs and
benefits be developed in greater detail, as part of the project
development and value engineering process.
Package 3 creates some significant adverse environmental impacts. This
is mainly due to infrastructure works on the Chiltern Lines, having an
impact on the Chiltern AONB.
The proposed works will be disruptive to passengers. The extent of
this depends on the scheme design and the scope of staging works, and
has not been assessed in detail at this stage.
In order to consider the case for enhancements to the Chiltern route
without further enhancements of the WCML, a revised version of package
3, package 3A, was developed which excluded WCML infrastructure works.
The cost of package 3A is approximately 30% less than that of package
3. Depending on the assumptions made in relation to rolling stock
procurement whilst retaining timetabling contingency to assist
recovery from delays and incidents results in package 3A having an
indicative BCR of between 1.30 and 1.19.
8.1.4 Package 4
Package 4 entails further works on the Chiltern Line between London
and the West Midlands, in an attempt to further improve the journey
times to the West Midlands. It includes a number of additional
infrastructure schemes, and is forecast to cost in the region of ^15.1
billion.
In this package it should be possible to reduce the journey time
between London and Birmingham to around 64 minutes, assuming a single
stop. Typical journey times to Manchester remain as at
121.5 minutes as in Packages 2 and 3.
Depending on the assumptions made in relation to rolling stock
procurement this package has an indicative BCR of between 1.1 and 1.0.
This BCR may change should the forecast scheme costs and benefits be
developed in greater detail, as part of the project development and
value engineering process.
Package 4 does have some significant adverse environmental impacts.
This is mainly due to infrastructure works on the Chiltern Lines,
having an impact on the Chiltern AONB.
The proposed works will be disruptive to passengers. The extent of
this depends on the scheme design and the scope of staging works, and
has not been assessed in detail at this stage.
8.1.5 Package 5
Package 5 involves additional infrastructure works to enable the
Chiltern Lines to become a viable alternative to the West Coast Main
Line as far North as Stafford. This package is likely to cost in the
region of ^19.6 billion, but running trains onto the northern
stretches of the WCML via Chiltern is may prove too technically and
operationally challenging. A considerable amount of additional work
would be required to assess whether this option is feasible
Package 5, if possible to implement, could allow a limited number of
extra services (notionally 1 tph to Warrington and 1 extra tph to
Manchester) to be operated via the Chiltern Line. It is not clear that
there is any significant demand for these services. It will not impact
on journey times achieved in Package 4. Typical journey times to
Manchester will remain at 121.5 minutes, with typical times to
Birmingham at around 65.5 minutes.
Depending on the assumptions made in relation to rolling stock
procurement this package has an indicative BCR of between 0.93 and
0.85. This BCR may change should the forecast scheme costs and
benefits be developed in greater detail, as part of the project
development and value engineering process.
Package 5 is the most environmentally damaging scheme, and has a
number of significant adverse impacts in the Chilterns AONB and
elsewhere.
The proposed works will be disruptive to passengers. The extent of
this depends on the scheme design and the scope of staging works, and
has not been assessed in detail at this stage.'
