Hi Signalling Professionals:
Recently, I am reading about the explanation of anti-preselection function for interlocking found in the IRSE textbook (Railway Signalling by O.S Nock). As I read through, I acknowledge that British railway does have this circuit design consideration for the signalling system
However, for the railway system I am now currently working at, do allow route pre-selection function, is that mean this is not a very good design of interlocking ???? I am thinking why do they not include anti-preselection design in the signalling system as how the British design their signalling interlocking.
otherwise,points might move unexpectedly, if the route setting is stored in the computer based interlocking. I hope someone can clarify this for me, if this is not good design for sure, i should ask the contractor to carry out rectification as required for future extension project.
thanks
