Hi Peter
I have been working through the control tables for the 2006 exam however if you could address some concerns I have?
171A(M) do you not have to take into consideration opposing locking from 122D(M)?? also if the signalman keys 228R then sets the route the route would the route not set up to 225B locking 225N? So therefore you need to consider 122C(S) as well?
It a horrendous set of controls to complete in an hour, my first attempt took around an hour excluding the point controls.
My experience is with NIR controls so most of our interlocking would not contain complex swinging overlaps.
Cheers,
Darren
Also I am unsure about the route setting from 175 signal coming of the branch, does this set to 159 signal and if it did would the O/L of 159 therefore not conflict with 122A(M), and would we not put 175A in the route normal for 122A(M) or prove train is timed to a stand at AG tc??
