I think the wording is "short breaks", but in reality I do not see anyone make any fuss about it.
If you buy the ticket in Sweden from Skånetrafiken you can break your journey, given that you start your last leg before the ticket expires (4am the day after you buy it).
I didn't find the rules for Danish tickets last time I tried to find them. But when you go from Malmö to Hyllie the train crew is busy with the stops so I don't think they check or invalidate tickets. And I have never seen a ticket enforcement officer invalidating a ticket. So whatever the rules are you most probably will have a fresh ticket anyway when you get off at Hyllie.Edited: 12:38 pm, December 01, 2017
