The city of Budapest has called a tender for the renovation of the M3 metro line.  Line M3 is the longest line of Budapest Metro and it runs in a north-south connection parallel to the Danube on the Pest side of the city. Apart from the southern terminus Köbánya-Kispest, all stations are underground. The tender has been delayed for months because of questions over funding as well as substitute buses that will operate along the line while it is upgraded.
