Bulgaria plans high-speed railway between Sofia and Varna

The planned high-speed line between Sofia and Varna (with a branch via Ruse to Bucharest) is designed for speeds up to 350 km/h and would cut Sofia–Varna travel time from 7h35 to about 2 hours. It is envisaged to be built via a concession/PPP model; as of 2023 the source reports coordination meetings with Bulgarian ministries and local authorities, with no construction cost figures given. Wikipedia's "Rail transport in 2030" list (citing Railway PRO) lists the project as an expected 2030 opening without an exact date; no dedicated Wikipedia article on the line itself exists.
