Route merging using TSRE Route Editor

[f522]

Hi!
I found a route merging instruction on this website (https://www.onrails.eu/viewtopic.php?p=58567#p58567) which is very simple and easy but I couldn't understand the calculation and conversion part of it anything else worked as written in the post. Can someone explain the calculation and conversion part of the thread to me?
Thanks!

PS: I reached out to the post author on the website but he is been in active on this thread since 2021

My understanding is if both routes have real-world locations that overlap correctly, conversion shouldn't be necessary.

I'm going to editorialize a bit here. I generally consider merging routes a poor idea. First, it may mean that your computer has to load a lot of files that it might not need otherwise. Second, unless one has hours and hours in blocks of free time, running an activity across long routes often requires saving then restoring a saved activity, which kind of destroys the point of merging routes. Third, many routes, even those sold or made available by the same entity may not even have the same scenery objects, track layout, etc. When running an activity spanning such merged routes, even if they can be successfully merged, it may be painfully obvious to the player when his/her train "crosses the border" from one route to the other. Just my $0.02.
