A quick clarification of " Shunt exit/entry " signals would be much appreciated. which way is which? whats defined as entry and whats exit? which way should i be looking?
Good question Ross and it's something that I had to wrap my noggin around as well. As with most of the signals in RW i'm not exactly sure how they were intended to work. What I've done is use Entry signals at the start of the siding and Exit on the siding tracks. Take a very simple siding as an example, where 1 track becomes 2. I used the entry swith for the train coming towards the switch, the train then has a chose, continue strait or throw the swith and go into the siding. This is my entry switch and will show red for allowing the train to continue on the main and white to go into the siding. Now coming from the other direction I've place two exit signals before the switch the logic being, if the exit signal is read on the siding the switch is not thrown and you need to throw it before leaving the siding. On the mainline the loging being if it's red it means the switch is thrown for the siding and not for continuing on the main line, thus it must be thrown.
I hope this helps a bit, but as I said I myself am not fully sure exactly how the RW team designed the signals to work.
