I think that the first two legs will be Nordjyske Jernbaner, the last DSB.
Exactly right. Nordjyske Jernbaner operate all rail services north of Aalborg. From there there are usually hourly DSB InterCity Lyn services
directly through to Copenhagen, plus one hourly connection to Copenhagen with a transfer in Fredericia.
I think Rail Europe is getting things wrong.
FormerBritInMe should be able to make their journey with only two transfers, that being in Hjørring St. and Aalborg Vestby St. So two NJ trains and one DSB train. The DSB InterCity Lyn service from Aalborg to Aarhus H changes route number there, hence the confusion, but carries on directly to Copenhagen. I can confirm, I've done the journey several times.
Yes we are arriving on a ferry, the Smyril Line from Iceland.
Using RailEurope I am able to see the itinerary (DSB's site did not, perhaps because a non DSB operator is involved?). However when I try to buy tickets I get a message "Sorry we are not able to confirm your booking". Perhaps it is too soon to reserve for a November trip? I was able to reserve trains on the DB site and Eurostar with no problem.
Thanks for the info on the stations and terminals. I will have to check to see where Smyril docks.
That might be because you cannot reserve your seat on NJ services or perhaps it is indeed too far in the future. DSB only allows you to book 3 months in advance I think.
Denmark's ticketing system is unfortunately a bit convoluted and tourist unfriendly. Basically all Danes use a pay-as-you-go smart card for their journeys (regardless of the operator) called RejseKort. There is now also a mobile app which works in much the same way. As far as I am aware, the new mobile app is available to everyone, but the physical card is only available to locals. You can still get regular single, return or day tickets, but sometimes only through the app of the respective local operator, or on paper, but only select places. It's a bit of a mess.
So my recommendations are:
1) For long distance trips book online via. DSB's website. They also offer discounted tickets (Orange Billeter), though with no refund. In case of delay or cancellation, it is valid for the train directly before and after the booked service. And, in my experience, DSB train crew tend to be quite understanding and forgiving. Regular tickets are valid on the day of travel (04.00 AM until 03:59 AM next day). So if you miss a train or would like to take an earlier or later train, no problem.
2) If you're not adverse to tech, I'd recommend using the RejseKort App when wanting to travel flexibly (i.e. in and around Copenhagen for instance). Here you only need to check in once at the start and then check out at the end of the journey. If you're planning to travel a lot by public transport, consider the 24h, 48h or 72h passes for either Copenhagen City (zones 1-4) or Greater Copenhagen (zones 1-99). Those can be bought at metro stations and major train stations as physical paper tickets or in the DOT app.
3) For all journey planning within Denmark, use Rejseplanen:
https://rejseplanen.dk/ - It is the most comprehensive journey planner and will show you precise information on the route (such as which platform your train is leaving from) and possible disruption, delays or diversions. There is also a mobile app version.
