1994 Question 2

[MikeMurphy]

Hi Peter,

Yes the question is for module 3.  I have taken it from the IRSE study guide July 2015 (Module 3 Study Guide 1 [Attached]).

Thanks for your quick reply and after reading the chapter and comparing the two answers, I can see where I'm having trouble in answering questions.

Chapter 2 in the study guide can be quoted as:
"The following fundamental requirements support the overall purpose of a signalling system. They are an amplified set of the requirements set out in the IRSE's Signalling Philosophy Review."

I can clearly see I missed the use of "purpose" in answering some of the 10 topics. I am struggling (although I understand the importance) the link between some of your points to the content the IRSE have provided in the study chapter and why they have not included these points.

For Example
"point 10 - Provide train running information to a plethora of other systems associated with the running of the railway and interface to the public", they have included no reference to providing interface to the public.

Thanks for you help
Mike
