In the summer of 2006 the line Burgas - Karlovo - Sofia was closed for repairs after an accident between Sliven and Tvarditsa. Until the end of July all passenger and freight traffic from the line was redirected via Yambol and Stara Zagora. Hence, at 25 July 2006 fast train 3622 (Burgas -  Karlovo - Sofia) leaves Yambol, hauled by locomotive 45 152.
