Working metro with usage under 100

[dupchurch]

So I couldn't figure out why all my metro is 100%, it's like people want to use them but they're not running, it still fills the need and I have no traffic issues at all. But this still bothers me, buses are same way, they fill they need even if there's no bus that stops there, but with buses you can see the routes/lines. But what I've figured out is I have way too many metro access points and not enough stations, realizing only stations spawn trains, so now I need to redo my entire metro system, my sims won't care either way, but now I know this, I do, I'm going to build it like a real metro with stations and lines.
But here's my question, how many trains does a metro station spawn? How many lines can a station efficiently serve, how many access points should there be per line?
