I have purchased a KORAIL Pass and naturally intend to travel on KTX from Seoul to Pusan.
Apart from the high speed route, what train lines in South Korea are particularly scenic?
I am thinking of travelling to Pohang and then trying to return to Seoul via secondary rail routes in the centre of the country, and deciding in the limited time that I have available not to visit Mokpo in the southwest.
Are there any branch lines that are especially scenic? It does not matter if the train trundles along at an average speed of 65kmh or so.
It seems difficult to plan detailed trips using KORAIL's English language Internet site version, as even when I select 'transfer' from the drop down menus, many journeys come back as 'no trains operating' or similar. This may be a programming bug, as I imagine that most lines have reasonable frequencies of trains.
