So it looks like the government wants to take a closer look at a £5 billion high-speed train link between Heathrow and Gatwick, dubbed ‘Heathwick’. Whilst this might have some use for people who already have to transfer between the airports, it would be totally pointless as a way of making some kind of joint ‘superhub’ for flight connections.
There is one simple reason for this – there just isn’t enough spare capacity at either airport to justify building a link between them.
Another problem would be that even if such a link might take a nominal 15 minutes between the two airport sites, it still would have to make multiple stops to pick up passengers at the three different terminal areas in the Heathrow site, and then make two drop-offs to cover the North and South terminals at Gatwick.
British Airways will no doubt be looking at the proposal with some moderate interest, as they are the largest hub airline at Heathrow, but they also have a sizeable network of routes from Gatwick, with passengers currently having to transfer between the two airports by bus. However, BA would still be much keener to see a third runway at Heathrow, even if that has been dismissed by the government.
Oddly enough, the £5 billion price tag is in the same ballpark as the (then) £6.9 billion Rugby Airport proposal, which would have delivered a three-runway facility halfway between Rugby and Coventry. Widely ridiculed at the time for being a white elephant no airline is interested in, it could have fast connections to London via the proposed high speed two rail line.
Even though there are a number of technical problems with the Rugby site, it is starting to look remarkably good value, when compared to anything coming from the current government, which, when it comes to transport policy, is remarkably lacking in sensible ideas.
