I've seen this happen numerous times now, and I'd like to find out exactly what causes it. Every now and then, I notice that my waiting passengers has suddenly jumped up to the max, although I know it should have taken a long time to get that high. Just earlier, I told myself "It's gonna take a little over an hour before I can send this train full again." Then, just minutes later, noticed my station was full of passengers!

Certainly not a bad thing, I just want to know why.
