HS2 - West Midlands Express

HS2 phase 1 provides a new railway from London to Birmingham Curzon Street and Lichfield. In the Birmingham area, a new station is also proposed at Birmingham Interchange, north of the current Birmingham International station. This blog examines a way to make best use of the new assets.

West Midlands Express

The new Birmingham Interchange station is deeply flawed as it currently stands. It provides no interchange with any existing public transport, and will rely on a "people mover" solution to connect to the existing Birmingham International station. The practicalities of a people mover mean that passengers from the local area, notably Coventry, will be highly unlikely to use rail to access Birmingham Interchange. This will serve to increase demand on the roads in the area. Not a desirable outcome.

In addition, the new HS2 line fails to provide any real new capacity for travel between Coventry and Birmingham. The current railway is just two tracks between the two cities and carries a slow stopping service for the many intermediate stations. Providing paths for a fast non-stop service in addition to the stopping one is a challenge.

The West Midlands Express proposal is a simple change to HS2 that solves both these problems.

The proposal is to construct two new connections to HS2. The first is from Birmingham Interchange to Coventry, allowing HS2 trains from the north and Birmingham to reach Coventry (the HS2 section around Birmingham Interchange has 4 tracks, so capacity exists for this). The second is from the existing lines east of Birmingham New Street, allowing trains from New Street to reach HS2.

The current service plan for HS2 includes the following: 3tph from Birmingham Curzon Street to London, 3tph from Curzon Street to the westerly leg of phase 2 (Manchester and Glasgow), and 3tph from Curzon Street to the easterly leg of phase 2 (Leeds and Newcastle). This gives a total of 9tph on the Curzon Street branch.

The West Midlands Express proposal would add an additional 3tph service on the Curzon Street branch. Trains would run Wolverhampton - Sandwell & Dudley - Birmingham New Street - Birmingham Interchange - Coventry - Rugby (shown in red). Extensions to Telford, Shrewsbury, Northampton and Leamington would all be possible.

Services would use either classic compatible HS2 trains, or trains similar to the Javelin trains used in Kent. Note that it is likely that trains between Birmingham and Coventry would be no faster than today using this route, as it is longer. However, it is the increased connectivity that is the justification.

The benefits of this service are clear:

1) Passengers from Wolverhampton (and the western West Midlands) to London would have a quick and easy change onto HS2 at Birmingham Interchange, avoiding the long slog between New Street and Curzon Street. They would also have much better access to the North at Interchange.

2) Passengers from Coventry to the North would have a quick and easy change onto HS2 at Birmingham Interchange. This would reduce the need for driving from the Coventry area.

3) Genuine additional capacity is provided between Coventry and Birmingham, with the new HS2 tracks becoming used for regional connections. This would allow an increase in the frequency of the stopping service.

4) The Coventry link provides a location for services from the phase 2 branches to terminate if there is no free path to reach London. This could increase the number of trains using the phase 2 sections, increasing their value.

In effect, the West Midlands Express proposal is similar to ideas already put forward for express services between Glasgow and Edinburgh, and between Liverpool and Manchester. In each case, the goal is to maximise the value obtained from the new railway infrastructure. In this proposal, it is places from Wolverhampton to Coventry to Rugby that would benefit.

Summary

The West Midlands Express proposal is a simple change to HS2, consisting of just two new junctions. Yet it provides greatly enhanced connections to the spine of the West Midlands, changing Birmingham Interchange from an embarrassing car park in a field to the hub of the national and regional network. Coventry and Wolverhampton particularly benefit from the proposal.

If you like the sound of the proposal, why not add a comment!

Birmingham Interchange is not an interchange

In my ongoing evaluation of HS2, its time to write about Birmingham Interchange.

Birmingham Interchange, is the HS2 station located on the edge of Birmingham. The site is next to the M42 1 mile east of Birmingham International station on the existing main line (the airport station). The intention is to add a cheap "people mover" to transfer passengers to the NEC, airport or existing station. There is also vague talk of a tram line (which doesn't materially affect the following conclusions).

The executive summary is that the plan for Birmingham Interchange is dire. Read on for the detail.

The key issue is that the station is completely disconnected from any form of public transport, meaning that the vast majority of passengers will be expected to arrive by car, for which 7000 parking spaces are planned. But the M42 in that location is one of the busiest stretches of Motorway in the entire country and well beyond its design capacity. This combination is a recipe for disaster. HS2 Ltd comment as follows (pdf, chapter 8):

Our estimate is that in 2033, the interchange station would attract a net addition of 1500-2000 cars trips to the area during the morning peak hour.

The chapter is worth reading to understand the analysis done. It makes no reference whatsoever to access by public transport. Only access by car is considered.

The station is intended to be used by passengers living in various parts of the West Midlands conurbation and in Coventry (nobody lives close enough to walk to the station). Its only fair to look at what these passengers do today, and what they will do in the future.

Many in the West Midlands conurbation currently use local rail services to access London trains at Wolverhampton, Birmingham New Street, Birmingham International or Coventry. With HS2 there will be no direct access to the new line by local rail at any of these locations.

Residents in the west of the conurbation around Wolverhampton can currently travel to Wolverhampton station for their long distance service. HS2 does not serve Wolverhampton, so those passengers will either use the existing service (assuming it continues) or drive to Birmingham Interchange. (The official document assumes Wolverhampton will use the city centre station, but they can't as New Street and Fazely Street aren't integrated)

Residents in the centre of the conurbation can currently use local rail and buses to access New Street for their long distance service. Since the HS2 station in Birmingham is disconnected from the local rail network, there will be far fewer uses of the local network to access the long distance services. Thus again, passengers using HS2 are most likely to use a car to access Interchange. (The official document assumes these travellers will use the city centre station)

Residents of Coventry currently have an excellent three trains per hour service to London. This will be scaled back after HS2. Passengers in Coventry will be encouraged to travel to the Birmingham Interchange station instead. Which again means a car. Certainly no sane person would take a local train to Birmingham International, then a "people mover", then an HS2 train. (The official document assumes these travellers will use cars to access Interchange station)

Taken together, HS2's Birmingham stations are a recipe for a massive increase in car journeys.

However, there is a catch. 1 in 3 households in the West Midlands don't own a car. So, by forcing car access, HS2 manages to reduce the overall mobility of the population!

Moreover, what has long been understood by those in the rail industry is that once people start their journey by car they are more likely to just keep on going by car. If you're driving from Wolverhampton to eastern Birmingham, why not just keep on going and drive all the way to London, or if you're in Coventry why not carry on driving to Manchester or Leeds?

It turns out that the rail network is absolutely dependent on good interchanges and junctions, where local journeys can be fed into national ones. HS2 ignores over 100 years of experience of what makes railways work by not buliding proper interchanges.

Interestingly, the London stations on HS2 are planned to be integrated with the local networks, at Euston and Old Oak Common (although the Old Oak plan is far from certain at this point). It is clear to me that Birmingham has drawn the short straw here. The effect of HS2 is to boost car journeys within the West Midlands area and reduce demand on the local rail network.

Given the lack of integration, especially relative to London, it is patent nonsense that Centro, the publicly funded body for public transport in the West Midlands, is supporting the current HS2 scheme.

Summary

Overall I think HS2 is a bad project and there is a better and more cost-effective approach - HC-Midland. However, my position is far more nuanced than that of the "anti" brigade. For starters, while the route through the Chilterns isn't my preferred choice and is far from ideal, I don't think that aspect of the scheme would be disasterous if it were to go ahead.

However, I am utterly clear that both HS2 Birmingham stations are unfit for purpose on basic transport grounds.

It is simply unacceptable and irresponsible in today's world to build a station whose only sensible access is by car and then have the cheek to call it "interchange". That mistake is compounded by the lack of integration in the City Centre.

In summary, there has been a lot of arguing about rail capacity, the business case and the importance of the environment. In my opinion, not enough focus has been placed on whether the line's stations meet basic transport criteria. Sadly, HS2's Birmingham stations fail spectacularly on those basic transport criteria.

Improving HS2 - Birmingham central

While my previous blogs have discussed alternatives to HS2 that I believe are better, I also want to write about options to make the current proposal more palatable. This blog focuses on Birmingham central.

One of my main criticisms of HS2 is that it doesn't meet the government's remit of a line from London to the West Midlands. The central Birmingham station of Fazeley Street only serves Birmingham city centre. It is completely disconnected from all other local railway lines, 5 minutes walk from Moor Street and 10 minutes walk from New Street. As such, there is no ability to travel on by train to the rest of the West Midlands, hence my claim that the remit has not been met.

The main issue in Birmingham is that New Street station is beyond capacity already. There is currently a large investment going into the station, but appallingly that investment will provide no new track-level facilities. As a result, Birmingham is going to face issues whether HS2 arrives or not.

HS2 Ltd's choice of Fazely Street just to the East of the city centre on a brownfield site is not by itself a bad choice. However, HS2 Ltd has had a failure of imagination by proposing it on its own. It is also a huge failure by being designed as a terminus with no possibility of future conversion to a through station.


View Larger Map

The Fazely Street site is the empty land on the right. Moor Street is centre right, New Street centre left and Snow Hill top left.

The distance to Moor Street is actually fairly small, so the first thing that must be done is to create a single station concourse that unites Moor Street and Fazely Street. This should also be under a single station name, say Birmingham Central. However, most trains in Birmingham serve New Street, and that is significantly further away. This is where imagination is needed...

Step 1 - lower the HS2 platforms into the ground. As the ground is undeveloped, digging a big hole and putting the station in it isn't nearly as expensive as building a tunnelled underground station. By being below ground level, it provides the ability for future generations to convert the station into a through station by building tunnels onwards under the city centre, perhaps to serve Wolverhampton or the main line to the Bristol. A terminus station is incredibly short sighted and will never permit future generations that option.

Step 2 - build a new station at ground level on the current lines into New Street. Now that the HS2 platforms are below ground, there is plenty of room for a ground level station on the current lines from New Street to Coventry and Tamworth. This station will need lots of platforms to be effective, due to step 4.

Step 3 - integrate Moor Street, the HS2 platforms from step 1 and the classic platforms from step 2 into a single station with a single concourse. The concourse would run South West to North East effectively along Park Street. All platforms would be served by escalators from this single concourse level built to the highest modern standards. This unified station would be known as Birmingham Central.

Step 4 - all services that currently serve New Street would serve Central. Some long distance services would only serve Central and would no longer serve New Street. This last point is critical, as it will provide the space in New Street (which cannot be expanded) for future growth in local services.

In summary, this is an imaginative proposal to create a new Birmingham Central station integrating Moor Street, new platforms on the New Street lines and new sub-surface HS2 platforms. Express services would only serve Central, while local services would serve New Street as well. This fully integrates HS2 with the local network and makes a huge difference to the viability of HS2 as a West Midlands service rather than a Birmingham city centre one.

Overall, I oppose HS2 because I think there are better alternatives. However, if HS2 does go ahead, this is one change that I believe to be absolutely essential.

Update: This proposal is similar to this Arup proposal "Grand Central", suggesting it is feasible and practical.
