I am away for the weekend, so I'll look at these early next week.

Sure you'll be OK with that, even if those monitoring "quality of service" consider unacceptable

I have had a look and will post an attachment with detailed comments in a day or so, but for now a high level response.

These are pretty good- lots of quibbles but in essence sound for the basic locking and certainly a gallant attempt at the more esoteric stuff [foul tracks not quite right, swinging overlaps mainly recognised but the controls weren't, time of operation locking is BOTHWAYS but only when the facers ar not themselves hard locked one way as they are for (W) routes!]. Frankly for the IRSE exam it is probably more important to concentrate on producing AT SPEED Control Tables of this standard rather than improving the nuances of presentation but I will be pointing out so "quick wins" to get a few more of the marks that are going.

I remember getting a text (or was it email) from one of my students who had sat this paper which certainly started "Nasty, nasty points!" They did OK though even though they hadn't attempted one of the routes- got a Credit which I know was actually discussed carefully by the examiners as it was borderline Distinction- once the results were declared, one of the examiners found that they knew the student and were suprised they had actually done so well, seeing as they had never been in a Design Office and had little experience- showing that careful studying, a little help on the way and exam practice pays dividends.

Quite what the eaminers got from getting candidates to do the CTs for two so related points I do not know- perhaps they thought that since they were quite heavy, there might be some economy of time when doing the second of them, but to me it was a lot of time and effort yet displaying the same knowledge (or lack thereof). Still they have their job to do in the way they best see fit; what the candidate needs to do is accept that the "exam is what the exam is"; speed is more important than precise correctness and therefore tailor their preparation accordingly.

Details to follow,

Dear Alex,

As the 'nasty, nasty points' writer, I can confirm that you shouldn't get too bogged down in the small stuff. As long as you can handle the main elements of the CTs, and it seems that you can, you have plenty of time to get the rest.
Try to understand exactly what the 'extra' locking does, and once you can relate it to a train move (or more likely what you are preventing) then it will become clearer.
Good luck.
Lynsey

Hello Peter and Lynsey,

Thank you for your comments with respect to my answer on the 2005 Point Control tables.

At this point, my approach to answering the past papers have been to treat them as revision assignments and I have not done them to stict exam conditions. Hence have spent more time in making sure my answers for entries like TOOL and Swinging Overlaps are correct and to tap on the experience of Peter, yourself and others who want to volunteer their views.

So thanks for you comments especially with respect to real exam conditions.
