2017 Q8 - AC track circuits - Boris_MTM - 17-08-2018

We conducted a 'mock' exam using the previous years paper under Exam conditions. Attached is my attempt at Q8 which concerns the AC Track circuit.

Some feedback would be beneficial. I have done further reading on AC track circuits since attempting this question but would like to know if was on the right track on the general theory.
