Dear PJW and all,
Attached is my attempt to the 2015 exam question.
I would like to ask for Point CT of 121.
Is it appropriate to include also 157A(M) in the "Points called by routes" ? There are several consideration in my mind.
(1) Set 121 to reverse to avoid train approach 122 accidentally when 157A(M) is set
(2) CP consideration
(3) While setting 121R will essentially reduce the availability of 161OL
Thanks
