A Metro ride from New Garia to Ruby will cost Rs 20, the carrier said on Tuesday.
There was, however, still no word on the inauguration of commercial services on the upcoming stretch, part of the larger New Garia-Airport (Orange Line) corridor.
The fare structure on the New Garia-Ruby stretch has been approved by the Railway Board, Metro Railway said on Tuesday.
A ride between New Garia (Kavi Subhas) and Ruby (Hemanata Mukherjee) station will cost Rs 20.
There are three fare slabs — Rs 20, Rs 10 and Rs 5 — on the 5.4km stretch, which has five stations.
Once the stretch becomes operational commercially, New Garia will be the first Metro station to serve as a transit point between two Metro corridors — the Blue line (between New Garia and Dakshineswar) and the curtailed part of the Orange Line (between New Garia and Airport).
The switchover of passengers between the two Metro routes will be seamless and on a single-ticket system, said Kausik Mitra, the chief public relations officer of Metro Railway.
A ride from Dakshineswar, the terminal station in the north-south Metro (Blue Line), to Ruby would cost Rs 45, the maximum.
There are four more slabs, Rs 40, Rs 35, Rs 30 and Rs 25, for a switchover between the two lines, the fare structure shared on Tuesday showed.
The CRS approval for the New Garia-Ruby section came on February 7.
The 5.4km stretch was initially supposed to have been operational by the end of February.
