I'm also assuming there's parking.

Out of curiousity why are so many signalling engineers awake at 06:12 AM [18] on a Tuesday morning, since that was the forum's highest usage? answers on a postcard.

Thanks in advance

I was asked to give details of the points CT that I used as a blank on the wipe board (note that some suggested "Simplified NR 11202" and "column" style are already in the mod3 section). Hence the attachment.

This is based on NR 11202 but with some slight differences.
There is often confusion created by this style with the points N to R and points R to N split vertically. I feel one reason for this is that the traditional column order lists tracks in the first column, then the calling routes, then the locking imposed by routes. Since the locking is in the OPPOSITE sense to the calling it is obvious that the route entries need to be diagonally transposed- what is calling in one direction must be locking from moving away from that position to the opposite. My belief is that putting the track locking separate to the other locking confuses the situation- thus I have changed the column order i.e.

col 1: those routes which, having first ensured the points are available (=correct or free to go), then places a call on them

col2: those tracks that ALWAYS lock the points (i.e. those immediately over the point end(s) and those that are foul of the points (lock the points in one direction and not the other- sometimes whether or not a track is foul is conditional on the lie of ANOTHER set of points)

col3: those signal routes which when approach locked must lock the points (since a train may be unable to stop prior to the signal that had been cleared but has now been replaced)

col4 etc: those tracks that are situated between the protecting signal and the points that must impose locking on the points once a train has been signalled and entered the route. Points beyond the exit signal must be released once the berth track has been occupied for the relevant time, but if there are track circuits beyond the signal prior to the points these must not be so bypassed and hence "outside the brackets"

Special Locking. I don't feel that it is worth putting Time of Operation loking and Swinging Overlap (aka counter conditional) locking on the blank. Hence the wide right-hand column for all this stuff as required. Indeed it would also be the place to show point-to-point (for example the GF and the trap points on the Watford example). For illustration the blank I show has drawn the entry for T of Op, but I'd only do so on a particular exam example if it were actually needed on that point; I have placed it halfway down the page as the obvious place to me for specifying locking that applies to points both ways (N to R and R to N) as it saves writing in a lot of identical stuff twice.]]>

Other elements of the event will be more general. To give a flavour of Past Questions of various IRSE Exam Modules for which useful background knowledge could be expected to be gained at this event, see the other attachment. To be clear, we are NOT intending to give model answers to any of these at the event but there should be plenty of relevant stuff to help with at least elements of most. Those not intending to perform CTs should consider the range of the various questions prior to the event and actually have a go at answering a couple of the relevant ones to their area of expertise. You'll then know "what you don't know" and want to ask questions to find out about on the day.

Even those attending the event but with no intention of sitting for an IRSE module in 2008 should also make an attempt to answer some questions; even if you find it a bit of a struggle it ought to give an idea about what the exam is all about.

In the exam there is typically 30 minutes per written question- obviously you are learning, so it will take longer, but you are expected to turn up at the event with a few attempted answers.

The event organisors suggest that you use this site to post your answer and share your efforts and learning under this thread. If you do that in good time, there's a better chance of us addressing the issue which interests you particularly at the event.

Hope to see some response in the not-too-distant future,

Simulators will be used to assist in giving an overview of the implementation of Signalling Principles by an interlocking and thus the session should be valuable to many wishing to enhance their domain knowledge by gaining greater familiarity with the actual operation of a signalling system. Hence the event should be useful for newcomers to the industry and in particular those studying for the various IRSE exam signalling modules, not just Module 3.

Attendees will gain most from the event if they perform the recommended prior preparation. It is worth noting that nearly 4 months have elapsed since the Review of the 2007 Exam, and in another 4 months the 2008 examination will be uncomfortably close unless you are by then well prepared. Hence if your New Year's Resolution to study for the exams has yet to be seriously acted upon, treat this as a timely reminder to get down to it- tempus fugit!

Note that there is also to be a separate Study Weeekend in August more particularly targeted at specific preparation for the Module 2 and Module 3 examination papers; your studying should match this approach- first build up your knowledge generally and then in the last couple of months target the task which you must perform under examination conditions.

Don't forget that you can use this Forum to let us know if you have any particular suggestions for topics to include within these sessions. No promises but if you don't ask there is no chance that your wishes will be considered....
