With BMRCL expected to convert all its existing three-car trains into six-car ones, the power requirement is likely to jump by 73%. At present, the energy requirement of a three-car trainis 8.3 unit per km. This will increase to 14.4 unit per km for six-car trains.
BMRCL currently has two six-coach trains; the remaining 48 will be converted by the end of 2019. “The energy consumption also depends on other reasons like headway between trains and passenger load,” said a senior BMRCL official.
Presently, two trains running on the 18.2km Purple Line (Byappanahalli to Mysuru Road) have six-car coaches, however, Green Line (Nagasandra to Yelachenahalli) that spans 24.2km is expected to get its first six car train only in January. Purple Line is also busier than the Green Line.
On September 11, for instance, a record 4.3 lakh people took Namma Metro, including 2.3 lakh on Purple Line and 1.9 lakh on Green Line. Read more
