We will be traveling from Stockholm to Gothenburg and later Gothenburg to Denmark in August. I am trying to book the reservations online. Initially, I planned on using Trainline, which I recently used for all our reservations in Spain with no issues. However, when checking the schedules on both Trainline and SJ websites, I am seeing two totally different sets of train schedules. Is there more than one train company operating these routes and possibly Trainline shows only one line? My preference is to use Trainline as I find it very easy to use. Not so much with SJ as not everything translates, but they have more to choose from and if there are any issues/delays we would have more options for later trains with SJ.
