Railway Gazette have reported in September that there is going to be sizeable investment into train infrastructure in the Western Balkans.
Agreement has been reached between Albania, Bosnia & Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia to improve connections and journey times.
Progress is definitely needed of course, but at a cost to the throwback years of train travel enjoyed by this particular traveller despite the frequent discomfort & delays.
If the old way appeals to you too it is probably a good idea to plan some journeys in the near future. For inspiration you might like to read my book detailing my travels in the region, which is available on Amazon.
