Some time ago I decided to play with the steam engines and steam turbines going with a staggered design. This allowed me to remove the middle lanes of power poles, and the basic idea with single boiler looked like this:

Truth be said 'stop' can act practically as station; idea is to 'link' stops to share name and reference; simple as that

As per #1 - good to know.

I'd like to ask your opinions about small expansion of rails :

As standard rail signals are heaavily based on TTD, I'd like to ask of viability of cration of some sort of 'chained' signals? [therein called 'pre signals'] i.e. signals of 3 varieties:
- exit signals [working basically same ...

Please be advised - there is no place where I said it is the most efficient way of doing it in general; I said it is the mathematical way of optimizing waste/production [i.e. no 'stale' cycles on any point in production chain].
With your calculations for 10 BSP - [note - standard efficiency I claim ...

Maximum Efficiency, x1 factory, Wasteless Blue Science packs research[Science Pack 3].
