I wonder if your question isn't a little off though. If I'm coming home from a conference of other important event, that's more lax than trying to get there on time. If I have to be somewhere and it's really important and I can't miss it, I would likely take the slow train. I can build my schedule around that and be guaranteed to get there. However coming home means I can get there any time that I want, so I'll take the fast train. If I get the 1% train I am minorly inconvenienced but 99% sure to get home in 20 minutes.
