The question asks you to say "How you would carry out the investigation". You have put a lot down there about what you are going to look at but I think the examiner is looking for some clear information about who would be involved, what level in the organisation they are and what they will be tasked to do. In the UK context, this would be a question about Signal Failure Investigation and hence a discussion about confirming the driver's and signaller's reports to make sure you are investigating the right thing, the levels of testing that would be carried out (non-destructive and destructive testing) etc. You have implied a lot in your list of things to look at, but not said much about how you would use that information - eg what level of importance do you give different pieces of data and what confidence do you have on that source. Although it does not specifically ask for this, certainly in the UK context, the authorisation for return to service should be discussed, particularly between the scenarios of finding a fault and not finding a fault.

For part two I think you have done better but it is still a bit light especially in section i - you have listed some valid things but a) a few more would have been better and b) a brief explanation would, I think, be required to get good marks. In section ii, you have given more detail on each of your possible scenarios, but the quantity is a bit light for a good mark.

The former Railtrack Signal Failure Investigation document from RSSB, would be a good read for you to examine this further. Although this is dated 1999, the principle of the organisation of the investigation has not really altered and the current Network Rail version of this follows the same process.
