I shall attempt to comment shortly but in the meantime note that this question
Discuss the risks associated with allowing a second train into an occupied platform and the measures that may be taken to reduce these risks. Your answer should include the situations when this feature would be used and any assumptions made about the signalling system.
has some similarity to the 2006 question which was attempted recently: http://irseexam.co.uk/thread-1436.html
A suburban terminal station has platforms that can accommodate trains up to nine cars long. The service is operated by multiple unit trains of either four or five car lengths. All cars are 20m long. At peak times units may be coupled together in the platforms to form trains of up to
nine cars long. Describe with the aid of a diagram:
• The indications shown and the controls on the incoming signal when the platform is clear and when it is occupied.
and
• The arrangements to ensure, that if the platform is already occupied, a train will not be signalled into that platform if the platform cannot accommodate the combined length of the two trains.
The 2012 question seems to require an answer based on GK/RT0044 fom a UK perspective whereas the 2006 question clearly intended one based on "Lime Street controls" but these are far less applicable nowadays than they were historically.
