First of all many thanks for taking the time to review and comment. Much appreciated.
Looking at it now i've definetly produced a few "school boy" errors.
a) Now I remember the safety training, Hazard is anything that may cause harm/damage and
Risk is the chance and severity of what the hazard could become.
If I'm just writing down the hazards + solutions and not explaining the risks it could shave a bit of time of my answers. Would that be accurate?
b)Again I am including the risk in my answer. I agree I could have included more hazards to get the 4 marks. I did not know about the pipe on NR not being used anymore (I don't work on NR or ever have) but details like these I should hopefully pick up via general reading material.
c)Again I have included risks, eating away at my time. John bit of confusion here Flora is plants Fauna is animals.
d)I agree, looking at it now, "electrical and mechanical protection". Answers should be targeted towards this..... seems obvious now you have pointed it out.
Pt2 5) I agree that is a fair enough comment.
Pt 7) poor chice of words from me there.
To get the 9 marks should I have been aiming at identifying 3 hazards with 3 solutions for each :- bullet point answer fashion?
Your right my style and speed need to improve but hopefully that will come in time and with practice answering past papers.
I shall be posting as many attempts as I can to help myself improve and hopefully others.
Out of interest could you provide rough scores/pass/fail/grades so I can gauge my progress.
Many thanks Jerry and anyone else who wishes to comment.
As ever for the actual exam it does depend what you can do in exam conditions in 25 minutes without having thought about the question for more than a few minutes previously.
The drawings look too detailed and neat to do in those conditions!
You'd have been better off not writing full sentences. Cut the unimportant words, do for bullet point clauses- anything to get the ideas across in minimum words and time. You are not writing a text book.
I think you do need to mention RISKs but not each and every time. Some could potentially lead to Wrong-side Failure and therefore an accident such as collision or derailment bringing destruction / injury / death but others are likely only to lead to delay / disruption / loss of confidence in railway etc. You could have provided a table looking at items a-d (and perhaps looking at Sig and Telec separately for c) as the rows and the possible outcomes in a couple of columns, placing a tick if a fault in that type of cable could give the right-side failure (all) or wrong-side failure (only some). Indeed you might place multiple ticks depending on relative likelihood of faults both within a cable type and RSF/WSF; this is an example of an economical approach that maximizes marks per minute.
It was a decent length and legible.
You don't state your practices and as Jerry has indicated the examiners will tend to default to NR unless you specify otherwise. Certainly on several electrification projects I could mention, there is raised troughing 1m or so above the ground for the power cables as the means of providing minimum separation from the existing S&T cable in the SCT on the ground. Looks to be a but of a nightmare re accessing the railway in places and time will tell how long it is before it gets hit or starts falling over- mind you, given the quantity of civil engineering nowadays, perhaps it is built to withstand a tank and the piles go half way to Australia!
I will not go too much into technical content as Jerry has made some points which you seem to have taken on board. Definitely you should ensure that your answer explicitly reflects EVERYTHING within the wording of the question
You don't necessarily need to give 3 hazards with 3 solutions for the 9 marks, but it does sound a possible way of getting those marks. You are correct that you ought to have a plan HOW you intend to claim those marks and this sounds a plausible way.
The answer as it stands is certainly is certainly not far off a Pass; I have seen far worse attempts in July for people sitting exam in October. Have a word with a potential sponsor; you could perhaps hope to attempt the exam in 2018.
