The problem lies in the fact that it has been destroyed to make way for a white elephant, a costly and unnecessary railway line that will probably serve very little purpose and be very pricey to use.
Are you clairvoyant?
How do you know it will be a white elephant, it has not been built yet.
How do we know it will be unnecessary, nobody can use it yet so we have no idea of passenger numbers.
How do you know it will be pricey to use, no fare details have been published yet.
You also say it is a "vanity project". It was first announced by Gordon Brown and Labour, and has been endorsed by all the parties in power since (Coalition and later Conservatives). If it had been "just" a vanity project then someone would have cancelled it by now.
What is the alternative, keep building more motorways?
I happened to go in to Birmingham by train early (about 7:30am) on a Monday a couple a weeks ago. I got on at Solihull but the train had already stopped at a number of stations before it got to Solihull.
The train was PACKED. I could not get a seat. I was amazed at how many people were travelling from way down South to come to Birmingham, most I guess to get to work.
A train that can go from Central London (Euston) and get to Birmingham in 50 minutes (and then on to the North of England) will be a godsend for many workers, and will hopefully be an alternative to them driving in their car on motorways.
But note it is not JUST about speed. It is also about getting trains OFF the existing West Coast main line to free up space so they can add more trains to other cities. I remember a couple of years ago Virgin wanted to add a train from Shrewsbury to New St station but there was not just the capacity on the line or the stations (New St station is "full").
Other countries have thousands of miles of High Speed train lines. Spain has 3100km of high speed line (with 1800km under construction). France has 3220km and Germany 3038km. Even Sweden has 1706km. The UK has 1377km with 230km under construction so we are a long way behind many other European countries.
In years to come, as petrol cars become banned in many city centres, and driving is seen as "anti social", train travel will become more and more the "norm". Even Birmingham is now considering a congestion charge, as I am sure are other major cities in the UK.
Yes it is a shame when a historic building is knocked down, but sadly this pub had not been protected and was almost allowed to become derilict so knocking it down was almost the only solution.
But remember if Chamberlain had not knocked down buildings we would not have Corporation St, New St, the Council House, the Town Hall, all of which the city is proud off.
