In many countries, and the UK is no exception, the capital city is usually considered the centre of the country, though not geographically so. All British people do this but the English are the strongest in this interpretation. However, if we look geographically at the centre of England it is in the region of Birmingham that is the geographical centre of the country.
The rail routes were built to and from London so that such is the case that London is reinforced in this concept at being at the centre of things. However, for infrastructure planning, it would be better to see where this London centric view has been proven right and where it only illustrates the lack of decent infrastructure elsewhere.
If we take that as the case then we can look at Birmingham and see how the railway lines would radiate out from that city to the most important directions and destinations.
(This star could be equally valuable for roads and motorways. However, as we are talking about railways we will leave it at just that.)
The lines indicate the main routes to
1) - London
2) - Reading
3) - Southampton
4) - Bristol and the South West
5) - Cardiff and South Wales
6) - Chester and North Wales
7) - Liverpool
8) - Warrington, the North West and Scotland
9) - Manchester
10) - Nottingham
11) - Sheffield and Doncaster
12) - Bradford/Leeds and the North
13) - Leicester and the East Midlands to East Anglia.
Not all the possible routes are mentioned but the most important are. Other routes can diverge as the Nottingham route from Derby does.
However, we have to see what our forefathers built up in the nineteenth century. It should be remebered that there was no central planning of these services nor of any other. Basically thery started out as a group of investors got together to set set up a railway to connect to the next town down the line. The London to Birmingham line together with the Grand Junction Railway from Birmingham to Warrington(the Warrington to Earlestown line was already being finished) are perhaps the exceptions. Their promotors had already thought of connecting the capital to the up and running Liverpool to Manchester line (at Earlestown).The line northwards to Wigan,Preston and Scotland was already in the thoughts of rail investors if not on the drawing board.
After those the building processes were still very much piecemeal. This was mainly due to the need to obtain investors, plus the need to pass a bill through Parliament for each indiviual section. This was an onerous task but basically cleared the way for only serious offers to be considered and not fly-by-night fraudsters.
Thus it can be seen that when we look at the same or equivalent rail corridors from Birmingham they are far from being straight lines to a destination. A lot twist and turn through the countryside. This was to miss the land of landowning persons who did not wish to have trains running across their land disturbing the the cattle or sheep. Many of the same landlords were very vocal to have a station built next to their land for their convenience and use, but not on the land itself. - The original Nimbys.
Fortunately that was not always the case. There were also many an occasion when the land was too waterlogged/boggy (though that was an immediate problem at Chat Moss on the original Liverpool to Manchester railway). Also geological considerations made life difficult with hilly and slatey ground made it extremely diificult or even impossible, to make cuttings through the land or tunnels as well. These days those problems have not gone away but persist. The difference is that construction techniques these days have improved tremendously to make these problems beatable.
From those thoughts come the ideas that today we should focus our efforts on bettering the routes of our predecesors. New lines, line straightening plus signal updating as well as increasing the gauge where possible so that foreign goods´ traffic can run along our rails without having to be offloaded on to trucks. All these measures can be taken to better the travel experience for passengers as well.
