Info from Exam review- Headway
Module 2 specific comments:
  1. Take care if you use a simplified formula for coming up with the headway - the answer may be right but they are definitely looking for the "how".
  2. Once you have calculated the headway, use what you have calculated or say why you have changed the type of signalling for a given part of the plan.
Also, ALWAYS state assumptions. Use what is appropriate and justify why. Don't quote standards number verbatim as it does not show an understanding of what you are doing.
