I thank my hon. Friend for that very good intervention. I completely agree with him, and was about to come on to that point.
We need a new line between Surbiton and Clapham Junction to relieve capacity, and we strongly support the development of Crossrail 2. Those measures will help Portsmouth by cutting 10 minutes from the journey during peak times, as the train would not have to take the slow route avoiding Woking. However, it will still take about 90 minutes, the same time as it takes during off-peak times. The Wessex route study also proposes building an overtaking loop along the Havant to Guildford line that would enable faster services to overtake the slow services. If that was implemented, Portsmouth would be well on the way to having the same sort of services it had in the 1970s, when it was possible to get from Portsmouth to London in 75 minutes by train.
However, that is not all. That solution does not address the problem of connectivity within the Hampshire and Solent area. It is almost as fast to get from Portsmouth to Gatwick airport as it is to get from Portsmouth to Southampton airport, even though Gatwick is nearly five times the distance. To address the problem, all we need is the building of a chord at Eastleigh, or increasing the junction’s capacity to enable a train from Portsmouth to head south as well as north at the junction. That would enable a direct service from Portsmouth to Southampton airport and Southampton and save a lot of time.
The existing route to Eastleigh is made up of a number of single-track sections. Those have to be made into double-track sections, which together with upgraded signalling would enable service frequency to be improved, which would help to attract passengers. Network Rail estimated in its route utilisation strategy that that would cost £135 million. The improvements would not only help Portsmouth connect with its neighbours, but enormously improve the journey for passengers getting from Brighton to Bournemouth and Weymouth, and from Weymouth to Basingstoke, Winchester and London.
When high-voltage electrification of the main line takes place, train speed can increase and we can start getting the same level of service that the rest of the country enjoys. Overhead electrification in the region, as already partly allowed for in the electric spine proposals, would make a big difference to train speed, and I would like that included in any proposal. It would make technical
sense. Modern rolling stock uses alternating current motors. Converting high-voltage AC from the national grid down to 750 V DC for the third rail and then converting it back to AC on the train to power it makes no sense at all. We already know that the South West Trains Desiro fleet is unable to operate on some parts of our lines at high speed because there is not the power capacity in the trackside equipment to permit it. High-voltage overhead electrification overcomes those problems.
Those measures would help improve productivity throughout the region. They would certainly help transform the economy in Portsmouth. In the “Rail Value for Money Study”, Sir Roy McNulty said that we should make best use of existing railways before considering new investment. The cost of the improvements as outlined is extremely small compared with that of new rail projects, such as High Speed 2 or Crossrail 2. There have been practically no major infrastructure rail projects on the line since 1967. The line from Portsmouth to Southampton was electrified only in 1989. In 2007, there was an expensive package of signal and power upgrades on the Portsmouth direct line. Not only did those works overrun, drawing a large fine for Network Rail, but we still have constant signal and power failures right from the point that the supposed upgrade was installed. That causes massive inconvenience for a large number of our constituents and damages our economic prospects.
Passenger satisfaction on routes from Portsmouth to London is among the lowest in the country. The latest national rail passenger survey shows that just 60% of passengers on the route think there is sufficient room. I am surprised it is that high, given the three-plus-two seating of the suburban stock on which my long-distance travelling constituents have to sit on their way to London. I am sure that some of my colleagues will talk about that. We now have no proper long-distance stock on peak services on the direct route from Portsmouth to London. Portsmouth passengers give a huge thumbs-down to the value for money of their ticket, with just 31% feeling satisfied.
Most of what I have covered is not new. It has been analysed, but nothing has been done. The measures would make journeys faster and have a major effect, taking people off the roads and making it easier to move around the whole area. The growth in passenger numbers on the Manchester to London line has increased by having services every 20 minutes. Increasing the number of trains an hour would be expected to help increase the numbers of passengers who travel by train in our area. The impact of faster trains on the economy along the Solent region, including a fast train from the south-west region and from Portsmouth to London, would be a massive boost to the southern powerhouse.
We must also remember our friends across the Solent. I am delighted that my hon. Friend the Member for Isle of Wight (Mr Turner) is here. I know he will have a lot to say. There are commuters who travel from the Isle of Wight to London every day. The Isle of Wight is a vital part of the regional economy. Its trade passes through Portsmouth with Wightlink and Hovertravel, and through Southampton with Red Funnel. I am delighted that a new operator, Scoot, is coming on to the Portsmouth to Cowes route. Improving rail links to the ports will help the Isle of Wight develop as a place to visit and to do business, and it will help the ports, too.
The Chancellor, while looking at the opportunities that could make up the northern powerhouse, must not forget the goose that lays the golden eggs in the south. The south requires only incremental amounts of investment to continue increasing production.
Portsmouth would be transformed by having a fast train service to London and along the Solent region. Any investment in our infrastructure will have an immediate impact on the local area, not forgetting that South West Trains already contributes £374 million per annum to the Exchequer, which could be reinvested into making that investment happen. I know that other Members will be talking about the quality of trains and the impact on their areas, but I hope that this debate will put down a marker to ensure that our rail infrastructure is upgraded to the same level as the rest of the country.
