A minor point- you say you have "solved"- do remember that an IRSE question does not just have one correct answer, there is not an unique solution. However you have offered one very valid response.

I liked the table approach; it was very clearly set out.
I think that it dealt well with the differences.
Some confusion between the various different type of possible crossing with full barriers and those various ones with half barriers. Better to have chosen one of each for comparison and then perhaps refer briefly to the variants later.
It was not so good at identifying the various factors- many were there but not so clearly identified.

I have made some alterations in track changes and also embedded comments in the attached.

It was definitely a good effort and a clear pass even as it stood. To have raised it above that did not need more material (there was plenty) but to have demonstrated a little more understanding of the rationale. Instead of as many lines of entry, a little more text within each that explained how the particular feature contributes to safety / results in a safety hazard would have improved markedly and thus be a better use of time. Similarly the factors need to be made more obvious; to avoid needless repetition given your initial answer then I think a separate table with minimum text within it tacked onto the end as shown would be effective; this only worked because you had the foresight to number the lines of your table; that is a good tip for others as enables easy cross-refs!

Thank you very much PJW.

Defiantly i will improve further.... and again i will come back to u.

One more thing,

PJW stands for?

[PJW]

They are my initials, by which I'd identify myself when signing a signalling drawing, as a tester or similar.

I use them on this site because my first name is Peter and this is the same as the person who set it up, so he "bagged it" first.

Actually thinking about it, goes back even longer into my past. When I got to the 6th form having completed "O levels" and studying "A levels", my maths master felt that the pupils were becoming adults and I think felt uncomfortable continuing to call us by our surname (family name). However it would be unthinkable to have gone so far as using our Christian name (as it was known back then- now more correctly called "given name") and therefore he either used someone's nickname (usually a familiar contraction of their surname or their initials. [Actually he had been a childhood friend of my mother's brother and so occasionally met him socially, so he'd call me Peter on such occasions, but I still didn't use his first name to his face (one just didn't do so back then, even as a young adult when first starting work. The world - at least the UK- has changed tremendously; look where that has taken us with the lack of respect for elders as evidenced by all the riots last week........

To be honest I often think of people as initials, much to the annoyance of a certain lady who I think of as MLJ but she seems very sensitive about her middle name...

... and you are still keeping mum about your J?

[PJW]

My point was that she doesn't appreciate the use of her middle initial as an initial at all, regardless for what it stands; from a purely practical viewpoint even in a relatively small group there is an appreciable chance of identical pair of initials, whereas the use of 3 reduces this chance significantly- another case of TLA. However I admit that "J "must be the least useful of middle initials in this respect for males of my generation at least, because it is so common; my middle name is John, but there are also many James as well I think.

@vinoth0106
I will emphasise PJW's points in that there needs to be more descriptive text explaining why something is important. For example:
1) Red aspects are safe!
2) A red aspect provides an indication to the driver the train must not pass this point. The aspect is fail safe, by design of the circuitry, that ensures even under degraded modes that a proceed aspect cannot be shown unless the locking can provide a safe route.

The examiners are after an understanding of why we do what we do, not that standards can be quoted or a high level understanding. It is a good attempt though.

@PJW, Peter
IRSEExam does social commentary! Interesting.

For me, the forename is always a Christian name, as being in rear of a pin is not on approach too. It pains me that English is being forced to change due to "fairness" and misunderstanding of how the language is supposed to be applied. It is one of the reasons why my new home country is across the little stream and far away from the UK.
