This web site is all about railway signalling. Its primary purpose is to describe the principles behind railway signalling in Great Britain, but some coverage of signalling around the world will also be found. The emphasis is on the older, mechanical signalling - that worked by mechanical levers and with semaphore signals.
I like this website because it gives me an idea as how things are done today especially if you want your signal box or even station upgraded from old fashioned ways where we used just switches for train control purposes only.
It's very good platform not really much complaints at least i can say so far its easy navigation system which makes everything clear when looking through different sections such as track diagrams etc..it give us information needed for our work daily life including safetyβ¦
Pros

Wide variety in terms software content, options & quality.
Good selection toolset that is useful both during planning stage
