On 2nd October at about 14:30 in the line section between Kostenets and Belovo there was a ladn slide, in result of which about 10 q.m. of rock slid onto the track and deformed a catenary line pole. Two fast trains (from Varna to Sofia and from Sofia to Yambol) were redirected via Karlovo. The railways organized bus transport for the passengers from next trains, which were scheduled to go through the problem section. Train traffic was restored at 20:30 on the same day.
