This is rubbish, if you have a 20 minute service on five lines then
thats four minutes between trains. If one train is delayed by three
minutes, therefore, it wouldn't slow down the next train by more than a
minute and certainly wouldn't affect the one after.

Policy is no justification - why should they all go through the loop?

None of which I find to be compelling reasons for poor service.
