Hi,

My October trip this year took me over land home from Greece via Bulgaria, Romania and Hungary.
I spent one week in Greece around Athens and on the spectacular Bralos Pass mainline section near Lamia - including Asopos Gorge, Papadia and Gorgopotamos Bridges - which is supposedly about to be replaced by a newly built tunnel section within the next few months.
From Thessaloniki, I continued to Sofia by MBV 360 - sadly with two bus replacement services, so not by train all the way - and via Vidin across the Danube to Craiova, Romania. As local football fans were just boarding a train, "Craiova" songs played on the station-wide speaker system. After a stop at the Iron Gates, my final overnight stay was Timisoara / Temesvar where old trams and railcars (Malaxa and as highlight a "Ferkeltaxe" ride) could be enjoyed.
