Very sad, but it is what you expect in today's world. Back in the 70's when I began travelling to Europe (I am currently in Bavaria), it was common to travel in a couchette (6 berths 2nd class, 4 in first class, mixed gender you just removed your shoes and were provided with a pillow and rug.) You had overnight accommodation and arrived in a city in the morning and went searching for a hotel. I had some memorable experiences sharing with other nationalities and languages. I must admit I prefer private accommodation today, probably because we travel with more expensive equipment like laptops but it is hard to find an overnight train now in Europe. I travelled from Paris to Portugal in 2011 but it was on a TGV to the Spanish border then a luxurious compartment with private ensuite and good but very late dinner. I tried to book Milan to Paris in 2013 but was unable to get a berth, not sure if that still runs. So we rush on high speed trains and book hotels on the net.
My only night trains are in North America (extensively in 2014) and I did both the Ghan and the Indian Pacific in 2012. Probably could not afford that now without the pension price. I doubt I will share with a stranger again on an XPT from Sydney to Brisbane or Melbourne.
Last Saturday I travelled (day) for 5 hours from Prague to Munich but have argued online that I considered it preferable to just 4 hours in a bus. Not the most scenic of journeys but pleasant nevertheless. Then there was the internet friend who, knowing I was enroute, sent a message, that I was probably at Prague airport. No way was my reply. I only fly when there is no choice eg Australia to Europe or across the ditch from Christchurch to Sydney. The journey is part of the holiday experience if travelling by train.
