Typically, when a country adds in a new ‘high speed’ line, or specifically an ‘additional direct route’ to it’s network, one of the main benefits is that this frees up other arterial routes to carry local traffic. So, if all the London to Brum traffic is on the HS2 line, then you should be able to get more frequent trains from places that used to share that route. Apparently that’s of no interest to this government, hasn’t been sold as a benefit, and hasn’t been costed or factored into how many cars they can take off the road. Or so all the train spotters tell me.
