I am attempting to make a train reservation for Sept 6th from Copenhagen to Stockholm on the SJ website, and see that starting on Sept 6th, there are no trains listed for about a 2-3 week period (It looks like a full schedule in October). I asked SJ the reason, and they said it had to do with planned track maintenance and they were waiting to get details before posting train times. Is this common - and is there a chance there will be no trains at all for a period between these two cities? I see the same thing when I look at Stockholm to Oslo a few days later. At what point do I make different arrangements?
Thanks in advance.
