The Main Train Station has been a typical reminder of the architecture from the communist era: massive and grey.
When I was a child I used to pass through the station with my parents and I remember the old brown escalators still working. I also remember that I really enjoyed standing on the steps and reaching the top without any efforts.
At that time the escalators stopped working one by one. The early 90's were tough years when state property was devastated, and the state didn't have the capacity to take care of its equity. So the Main Train Station slowly turned into an ugly reminder of the past times with its dark, stinky corners, greasy benches and homeless dogs. The escalators' colour became darker and darker, dust and rubbish irreversably damaged the mechanisms and they turned just into dangerous alternative of the stairs.
The reconstruction of the front part of the train station began in the early autumn of 1999. It's been in progress since then. The front square is owned and managed by the Municipality of Sofia which probably is the main factor for it's reconstruction. The building of the train station itself is owned by the state. For a long time there have been huge arguments between municipality and state concerning the status of the whole complex (building and square), but almost no progress.
I was happy to notice that some progress has been made in the modernization of the building itself. Apart from other minor improvements, probably the biggest one has been the replacement of the old escalators. Since 2006 half of them have been replaced and the first few are already running!
