Great.. I was tracking this loco in RDS for past few hours. Was in a mind set that the loco hauls DD back to MAS(as it was the link for 22625 in the morning)
It was showing constant speed of 90- 105 km/hr for a long time and suddenly some time before it showed 0 km/hr at Kuppam with LOCO BRAKE 'APPLIED' status.
I was thinking why DD (22626) stopped in Kuppam. But you cleared my doubt now. (That the loco comes back with 12640)
