Is entering Overrun Protection required as part of the exams as the 202 tables do not have them?

It is up to YOU to declare YOUR practices- there is no fixed link between IRSE and current NR although I must admit that the layouts are very mainline UK (but actually pretty much 1970s / 1980s).

Agreed the 11202 CTs do not have specific box; they reflect 1980s which was a time when the pendulum had swung away from providing flank tracks and before the reaction to certain accidents caused it to come back into favour again, albeit in a slightly amended form as Overrun Protection. They are very out of date for various reasons being implicitly for RRI but actually nowadays used almost exclusively for SSI; actually part of my day job is to revise them and yes there will be such a column that will make reference to a dedicated Overrun Control Table where all the gory detail will be shown. Indeed such sheets already exist for various sites and are frequently cross referenced from the Remarks / Special Controls column of 11202.

So IF you declare CURRENT NR practices then you should include. If you declare British Rail then you should not. I realise that as an individual who are having to learn foreign practices purely for an exam then you don't know where to turn. Don't worry too much; it isn't basic locking where the marks really are. In one way it is a frill; however I do suggest that it is worth including somewhere, the primary reason not being the actual marks you'd get but BECAUSE IT'LL PROBABLY GET YOU TO REALISE THAT YOU HAVE MISSED CALLING POINTS FLANK and there are goodly marks for those.
