https://edition.cnn.com/travel/article/europe-scenic-railways-underrated/index.html
The biggest issues for underrated scenic railways are below
・Autonomous units or railway companies cannot afford to advertise themselves.
・Transportations from a main airport or mega city do not have enough capacity to transport many tourists.
The former case can be helped by third parties like national governments. On the other hand, the latter case will be difficult to be helped, because it requires huge investment to increase capacity?
