Indian Railway has decided to increase the speed of trains up to 75 kmph (kilometres-per-hour) to avoid the delays caused by foggy climate.
In a notification released by the Indian railway regarding this, it is mentioned:
"A decision has been taken to increase the speed of the trains up to 75 kmph from the present 60 kmph.
As per this, all Zonal Railways MUST ensure that lines glow in yellow or black colour on all display boards including Signal Boards, Whistle Boards, Fog/mist indication Boards, and the locations where there are prospects for accidents on crossings.
These lines (yellow or black) MUST be visible, in case it is required repaint, this MUST be done before the onset of the foggy season.
On locations where direction Boards or Long-distance signals are displayed, this should be indicated by white lines using lime (sunnambu in Tamil)!"
