Need help understanding the use of Waiting Points ...

Sorry for being a pain but what do you mean by a "passing loop". Is this like a siding kind of thing? An example of this could be great using a default MSTS route or ECE if you can Only a short one that is.

It is like a siding for Americans I would guess - basically the track temporarily extends from 1 track to 2 tracks to allow trains to pass and then comes back together.
I'll try to find a shot from AE to show later.

The solution to your problem is to increase the number of passengers at the platform in question.The more passengers,the longer the train will wait.To do this click on the blue markers at the end of the platform in the AE and alter the number in the box that appears.

We already went through this lol

I've got it to work using the passenger number. Highest is 140 for the trainset (consist). So works perfectly with a bit of jiggling around with the number.
