I live in Oslo, but am from Sweden originally, and often take the train because of convenience. For several years in the early 200s, there was no train between Oslo and Stockholm except weekends, because of politics. During to the pandemic, we had no trains over the border at all for a year and a half. The service to Stockholm has to trail behind slow local trains, so takes two hours to get to the border. The service to Gothenburg is a Norwegian regional train with just a crappy vending machine (but it's only just over three hours, so that's fine), with no proper connection onwards to Copenhagen. SJ's Swedish trains often have to turn around in Malmö due to reasons, having to switch to the commuter train to Copenhagen.
The latest scandal is the electrification of the Trondheim to Sweden line, which is delayed so that it will still be closed during the Trondheim cross-country skiing championship, missing on the opportunity to transport Swedish fans by train...
