Should the Budapest Transit Center (BKK) sign the design contract by July 8, the renovations can start this year. The project would be realized in the fiscal period of 2014-2020.

The upgrade is badly needed as the line has seen no upgrades in the last 35 years of operation and has a daily usage of approximately 540,000 passengers, more than the entire rail nework of Hungary. The wear on the line is beginning to show, and technical problems threaten the metro’s operation and passenger safety.
