The Byappanahalli-KR Puram link was delayed, according to Yeshwanth Chavan, the chief public relations officer of BMRCL, for a number of reasons, including construction projects between the two stations, problems with railway line crossings, bus depot improvement projects at KR Puram, and decongestion plans by other civic organisations. The Commissioner of Metro Rail Safety (CMRS) must still test the link even if the majority of the work on it has been finished. The Byappanahalli-KR Puram link will be prepared for public usage once all testing is finished.

With 69.66 kilometres of operational metro network and 63 stops, Bengaluru now has the second- largest operational metro network in the nation after Delhi. The two primary lanes are the 39.34 km east-west corridor and the 30.32 km north-south corridor. The 750V DC Third Rail Traction on standard gauge is being used for the first time in an Indian metro rail project.
