I feel that could be resolved by adjusting ticket prices and providing alternative options, like regional buses/coaches. Another possibility is adding more doors to each carriage, spreading out queues across the platform, but at the cost of less seating
Where I am, the regional/inter-city train costs are very competitive with the alternatives, and sometimes enable more flexibility with travel. It’s still nowhere near the affordability of some parts of Asia though, and is overpriced IMO. My biggest gripe though has got to be only 2 doors on each carriage side, one at either end. And they’re narrow AF, good luck carrying a bike on board. What sadist designed these trains 😭
