I am working as a signalling designer in one of the UK Railway Company and this is my first forum entry.
First of all, I would like to say warm thanks to forum admin for accepting me as forum member.
I have joined a railway 10 years ago in the signalling design process working on several multi-disciplinary remodelling and renewals schemes rail projects.
I would like to know the situation where an automatic signal provided with a replacement facility operated from NX panel in Signal Box, can have an Entrance/Exit button.
I would much appreciate if anybody could look please into my issue and replay.
Kind Regards,

The signal normally has a button like any signal that would be an entrance or an exit, but the function is effectively pull to replace the signal, push to return to automatic.
An automatic signal can obviously be an exit from a controlled signal and hence if it is a valid exit when the entrance is selected, the button would take on the function as the exit when pressed.
