The two companies today signed an Memorandum of Understanding (MoU) in this regard.
The construction work of the 30-km-long corridor is already being executed by DMRC on behalf of NMRC. The structural work on the corridor, that will have 21 stations, is expected to be completed by March 2017.
"The assistance for O&M services would be rendered during the pre-commercial operation period of the NMRC and three years post-commercial operation period too. The agreement may be extended after successful completion of three years of commercial operations by NMRC with mutual consent," a DMRC statement said.
