My time in Croatia and Slovenia is at an end - I had a hell of a good time - so train #23 is the 1840 sleeper from Zagreb to Stuttgart. Unfortunately, problems with my carriage and another one mean that my single occupancy cabin is downgraded to a couchette which I share with two others. Luckily, some incredibly fast shunting by station staff to remove the failed carriages means we depart only 13 minutes late, and make up time overnight to arrive bang on time. Bravo!
