According to CR’s chief spokesperson VA Malegaonkar, the overall energy consumption has been reduced by a substantial 15% in the year 2010-2011 as compared to 2009-2010.
Eager to drive home the message of judicious use of electricity, the Central Railway (CR) has, in the previous year, managed to substantially reduce its electricity consumption by using a combination of new energy saving technologies and by applying simple energy saving tricks in its everyday operations.
According to CR’s chief spokesperson VA Malegaonkar, the overall energy consumption has been reduced by a substantial 15% in the year 2010-2011 as compared to 2009-2010. “If the CR consumed 7.63 units per gross tonne kilometre (GTK) in 2009-10, the number had come down to 6.49 units per GTK in the 2010-11,” he said. GTK is a unit of measurement representing the movement of one tonne of rail vehicle, including the weight of tractive vehicle, over a distance of one km. This reduction in consumption enabled the CR to earn about Rs51 crore in the 2010-11.
Elaborating further on the several measures that enabled the CR to save electricity, Malegaonkar said in specific sections of operations such as ghats, only single loco-engines were used even if 3 were available. Auxillary circuits, which consume high electricity, were turned on only when the train was in operation. Also, if the train was to halt at a particular location for more than 45 minutes, the loco engine, which enables the movement of the train, was turned off.
On the suburban section, the new trains purchased under the Mumbai Urban Transport Project (MUTP), which were brought into operations, also helped save electricity as their contemporary regenerative braking technology is designed to harness the mechanical energy lost through conventional friction braking system. Regenerative braking uses the electricity generated by braking, which is transmitted to the overhead wire.
