The line from London needs a new station called Birmingham Interchange some distance from Birmingham International Airport station to which it is meant to connect. This is ridiculous duplication and waste - the proposed station is not even on the west side of the M42.
Approaching the West Midlands conurbation it is logical to reduce speed to stop at such a station so a lower line speed limit can be applied thus aiding the flexibility of the track layout to permit its entry into Birmingham International Airport station. The trains could then continue up to Lichfield as envisaged. The paper gives us to understand that trains into Birmingham and those onwards to places further north would all stop at the Interchange thus making this proposal realistic.
This would then make Birmingham International the best option (a) to serve the airport and (b) to serve as an out of centre station for those trains that continue northwards.
As can be seen from the DfT proposal on the map from the HSR2 line into central Birmingham a chord is constructed at Water Orton to make use of the present corridor into the centre of the city.
The disadvantage of this is that it makes the line a cul-de-sac. This makes it essential for any traffic from the south to enter down the corridor and if that trafiic is intended to continue northwards then it has to backtrack through the same corridor to connect with HSR2 on towards Lichfield. Thus with this proposal the Birmingham International station is the only realistic option for through traffic.
However, that does not necessarily have to be the case. If HSR2 were directed through Birmingham International then it would connect to the WCML into the city centre. Whether the services terminate at New Street or not wouild depend on the need or desire to construct interconnecting lines in central Birmingham or even a new station at Curzon Street/Fazeley Street.
Is this a realistic option? or can the present inner-city stations be used?
What better than to quote the "do minimum strategy" report by ATKINS (High Speed 2, Strategic Alternatives Study, Rail Interventions Report, March 2010)
However in package 3 it is not possible to route trains to Birmingham New Street without them having to run via Leamington (even if non stop), Coventry and Birmingham International, and still maintain competitive end to end journey times. In package 3, because Coventry and International still have to be served, 2 tph will go via the (slow) Leamington, Kenilworth, Coventry, International and New Street route, and 2 tph will run on the faster, direct route to newly reconnected platforms at Birmingham Moor Street (Chiltern Railways´ main Birmingham terminus)
Birmingham New Street and Birmingham Moor Street are within sight of each other. A direct pedestrian route exists between the stations takes less than 5 minutes. A mobility impaired route has also been built.
Having an extra 2 tph call at
The traffic pattern, as envisaged by the ATKINS report,offers various alternatives (packages) depending on how much investment is involved (not just on the Chiltern HSR2 line). As we indicated in the previous blog (White Paper 2) the most likely options are Packages 3 and 4(Appendix A pages 77-83). These offer services from the London termini, Marylebone, Paddington and Euston into the Birmingham termini, New Street and Moor street. The destination mix depends on the number of services offered in total. However, in this document There is no proposal to build a new station in Birmingham and the Chiltern line would have only the necessary investment to upgrade - not a new HSR line.
The White Paper offers no clarity on the service patterns and says no more than that a new station is to be built and all Birmingham HS services will go there. More work has to be done on this. It is far too vague. The ATKINS proposals offer concrete solutions and are compatible with the construction of the HSR2.
The public deserves a better thought out document.
