The Overview of Simutrans-Extended features thread is missing a section explaining what is comfort and how it interacts/limits passengers. Honestly I currently control the wealthiest company on the server and still have no clue how comfort effects anything.
Thank you for pointing that out. Formerly, comfort was explained (http://web.archive.org/web/20130618023445/https://forum.simutrans.com/index.php?topic=1959.0) in the section dealing with revenue calculation, but I omitted to add the explanation for this back when I added the section on passenger and mail classes. I have now added comfort as a separate section in the overview of features (https://forum.simutrans.com/index.php?topic=1959).
Thanks, that clears things up a bit. I will use lower class bulk accommodation for some lines now to avoid overcrowding.
I've added a wiki page.
Excellent, thank you!
