Yes, that diagram is now looking much better.
The only obvious thing that you have missed is that the signals at the left hand end of loop A1 need to be 3 aspects so that they can show a caution in circumstances in which the signal controlling admission to station A is at red (need also to consider of braking distance and, if not, what to do about this)
I am sure that by working through this question you'll gain an in sight into the signalling of a very different railway to the type you are used to.
It will therefore prove its value as an exercise.

Attached jpg file is the updated version of single line layout which I have done. The suggestion you gave I’ll try later to see how it goes.
Thanks

Looking at your signalling, there are some inconsistencies and you have rather too many signals overall.......
I suggest you should draw a graph of the timetable. ....
