in the constant combinator, set T to a number 1-10
with "check circuit conditions" checked, the train should skip every stop except that one
what happens instead is it will go to every second stop, until it reaches the correct one.

You can also change the "wait until" on any station to something like "empty cargo" and you'll see that it will reliably skip those stations, but not the others.
(also, sorry I didn't see your reply for over 2 months, I stopped playing factorio for a while.)
