Realism should rule in infrastructure debate | Opinion | The Engineer.

So here we are again. Business case for High Speed 2, take five. In some ways  this reminds me a little of Lewis Carroll’s the Hunting of the Snark — not a  poem in several chapters, according to Carroll, but an Agony, in several Fits.  The progress of HS2 is indeed agonising, and the paroxysms of opposition do seem  fit-like. And, like much of Carroll’s work, many dismiss it as nonsense.

There are those who think that taking five tries at the business case for  such a large project smacks of desperation. Among those is Evan Davies,  presenter of Radio 4’s Today programme, who noted that the argument in the new  document had shifted from the increased speed of travel to the improvements in  carrying capacity. Doesn’t that mean you’ve run out of ideas, he asked transport  secretary Patrick McLoughlan yesterday.

But of course capacity has been at the centre of the strategy of HS2 from the  start, as readers of our coverage of the project will know. The  Engineer has been broadly supportive of HS2 because we’ve always spoken to  the engineers involved in planning the project rather than politicians, and  they’ve given us arguments that make more sense. Whether they make £50bn-worth  of sense is another matter, and that’s an argument worth having (and where our  support comes up against serious questions).

It’s the issue of capacity and alternatives which the latest study seeks to  answer. This government’s record with statistics is dodgy to say the least, so  its conclusions must be subject to scrutiny. But the assertion that upgrading  the West Coast Mainline to provide the same capacity benefits as HS2 would lead  to 14 years of service disruption and weekend closures should at least inject  some more realism into the arguments of HS2 critics.

It’s always seemed that suggesting the approach of upgrading existing lines  as an alternative has seemed glib, as though it would be easy, or cheap, or free  from any disruption. Whether or not the business case document is correct, there  can be little doubt that such a severe upgrade would cause a long period of  chaos. Other ‘simple’ fixes would surely also require more complex work than  might first appear — can you just replace current rolling stock with  double-decker trains without extensive rail replacement, reinforcement,  rebuilding of bridges, and station refurbishment to cope with extra  passengers?

If the report  refocuses the pro and con camps on the actual issues, rather than on rhetoric  which doesn’t address the actual engineering, then that has to be a good thing.  A project such as this needs to be discussed, and not in the context of  political point-scoring and hysteria.

The argument that HS2 will take express trains off the West Coast line and  allow it to carry more stopping services seems sound and is familiar to us. It’s  also argued that this would allow the West Coast to carry more freight, taking  heavy traffic off the road. The arguments are strongly dependent on the demand  for rail continuing to rise, and this is something worth debating — with  increasing internet capacity and ‘virtual meetings’, do businesspeople really  need to travel that much? If not, would non-business travel justify the cost?  Would people rather take the train than drive?

We idly wondered whether the arguments over HS2 would have been different if  the project were scheduled to start in the North, with phase one connecting  Leeds and Manchester to Birmingham and phasetwo completing the link to London.  Would there have been less opposition, with the plan more clearly emphasising  the connectivity where there is currently none? The cynical view is that of  course there wouldn’t – the opponents would just be saying “Why build the  line in the North where there aren’t enough people to use it? Put it in the  South where the trains are so full that the doors won’t close!”
