There's something to be said also for the rise and rise of smartphones and tablets. It's become a lot easier to pass the time on a long train journey than it used to in a way that you can't do when driving as you need to concentrate on the road.
excellent point - flexible working too and BlackBerrys allow people to be more productive outside of the work place than being sat in their cars.
That said, it is largely dealing with emails! Which themselves didn't *truly* exist 20 years ago. So a modern solution to a modern problem - not an evolution for a long-standing problem.
I think we are seeing a slight renaissance. It could be more daring, but there are signs. The current government (much as I hate them) does seem to appreciate rail investment as a stimulus better than predecessors.
The electrification scheme is massive, probably the biggest sign, and will benefit nationally.
In terms of re-openings, there has been Airdrie-Bathgate, the Borders is starting, there is the Chiltern to Oxford and of course its bigger brother, East West rail. Northern Hub is a tiny chord, but with huge impact especially combined with wires across TPE. Todmorden - again tiny curve but big impact. And how about Croxley, which I never thought I'd see!
London Overground is a complete refresh, and is changing how people perceive London, opportunities for employment & consumption, and overall expanding and redefining its core.
The new stations fund is a smaller intervention too. As the Cotswolds doubling finishes, the route via Kemble was announced too (local MPs no doubt helped, but still strategically important).
Plenty more besides. Between wires, line speeds, signalling, new lines, new stations, Crossrail, Thameslink, HS2 and other projects - there is a huge range and scope of development at every level and type.
So I suppose whilst there isn't one cohesive, united renaissance 'drive' - we ostensibly do have a disparate one due to the sum of the parts.
