There is a lot of discussion about the number of paths in Thames-Mersey. So, I will take a little time to explain the philosophy behind them:
When I was creating the paths, I took the approach of analysing where trains would go to and from, from a railway operators point of view.
Taking goods for example; following a wagon despatched from say Northampton to Chester, the wagon would run in a local pickup goods to the nearest marshalling yard, probably Rugby in this instance, the wagon would then be put in a long distance non-stop goods train from say Rugby Sidings to say Basford Hall Sidings, then the wagon would be put in another local pickup goods to it's final destination, Chester.
For passenger trains, I also took the logical analysis for how far local, semi-fast and express trains would radiate out from a specific location, such as Nuneaton for example.
So, I created a comprehensive set of paths that covered the main parts of the route. I did not take into account, for, example, that over some parts of the line there are separate Slow lines and Fast lines, with the attendant duplication of paths. However, I was careful enough that many of the paths from point A to Point B and from Point C to Point D would alternately use the Fast or the Slow lines where they run in parallel, so it would help the creation of AI traffic.
Some of you may have already discovered the 'hidden' new lines in the uncompleted Wirral Areas - when these are finished off in V4, there will be at least another 60-70 paths added to the total.
The other consideration, that should be addressed, is that many users simply want to use Explore mode, but having a great variety of paths like this, you can drive from almost any point on the route to almost any other point on the route.
Many of the shorter paths, have been included (such as the many small branch lines that join the WCML, like Newport Pagnall, Dunstable, etc. and also other lines that cross over the WCML, but don't necessarily connect to it) simply for completeness.
The main advantage of doing this, is that when you are bored from barrelling down the WCML at supersonic speeds, you can come and have a drive on some of the nice little short tracks and Cameo routes, just for variety. For example the small cross-country runs from say Madeley Town to Silverdale and from Blisworth towards Bedford are delightful little runs in their own right.
The other advantage of including the connecting branches, is for AI traffic; if you create your traffic timings right, you can have local trains arriving from or departing to the branch lines as you drive by on the main line.
Discussion in the forums has already solved the problem of too many paths by creating a Stored Paths folder and moving most of them into it to improve the startup times. I normally work with Windows Explorer as one of my main screens, so, dragging and dropping the required paths, consists and trainsets is only a matter of a few seconds work before you fire up MSTS.
