Norwegian Rail from Oslo to Bergen and back was excellent. Clean windows; the entire train was spotless and on time. Swedish Rail from Oslo to Stockholm was completely different. Engine trouble halfway, windows filthy (it looked as though we were locked in a heavy fog, yet it was clear. A few days later from Stockholm to Copenhagen was far worse. Keep in mind, all of our travel was “1st Class”. Windows filthy, very little accommodation for large suitcases, all of which would be fine if the train ran on time. A signal issue occurred at the halfway point, resulting in a three-hour delay, turning a five and one half hour trip into nearly nine hours. They announced, as we approached Malmo (just before crossing into Denmark, that Malmo would be the end of the line, requiring everyone to disembark to take a commuter rail train into Copenhagen. After everyone was lined up with all baggage retrieved from overheads and other storage areas, the order was countermanded. It resulted in all luggage semi-returned to storage, with aisles clogged with baggage. The train came into Copenhagen, after another forty-five minutes, at a remote track which was NOT in the main terminal, raining on the open track and platform area with the entire passenger group fleeing toward one five-passenger elevator to get to street level. Another quarter-mile hike was then required to get to a cab line in front of the main terminal. It made Amtrak look like the Japanese Bullet Train. It was truly Third World. Never again.
