Albania does technically have a very limited passenger service operating 3 times a week on Fridays, Saturdays and Sundays from Elbasan to Plazh and return.
They usually also run a service once a week in the spring from Shkoder to Lac and return altho it remains to be seen whether this runs in 2024.
Unlikely to be of use to you, but having been on it myself, it certainly is a novelty, if very dilapidated, no lighting, graffitied and smashed windows, tracks that look abandoned. Ex deutsche bahn coaches from the 80s hauled by old chzech locos.Quite surreal, and very cheap, usually less than a pound for a single ticket
