Correct, both ASR Shatabdis have more priority then both Kalka Shatabdis on this route. There must be some operational or medical emergency for sure.
In Winters, i have seen every year between 2010-2015 when i used to daily commute, during Foggy mornings Shan -E-Punjab, ASR Shatabdi and Kalka Shatabdi used to run one after the other with delayed departure from NDLS. ASR Shatabdi was allowed to overtake Shan E Punjab usually at Karnal and Kalka Shatabdi used to trail SEP till UMB.
So...
more... no chance of Kalka Shatabdi to overtake ASR Shatabdi unless some extra ordinary event. Check even current TT of Kalka Shatabdi, it has a run time of normal intercity between KKDE and UMB as it trails SEP.
please wait...Translate to EnglishYeah, you got it right! Both ASR Shatabdis are given more importance than both Kalka Shatabdis on this route. There must be some urgent or emergency situation for that to happen.
During winters, from 2010 to 2015, when I used to commute daily, I observed that on foggy mornings, Shan-E-Punjab, ASR Shatabdi, and Kalka Shatabdi used to run one after the other with delayed departures from NDLS. ASR Shatabdi would usually pass Shan-E-Punjab at Karnal, and Kalka Shatabdi would follow behind until UMB.
So, unless something extraordinary happens, there's no chance of Kalka Shatabdi overtaking ASR Shatabdi. Even if you check the current timetable of Kalka Shatabdi, it has a similar running time to a normal intercity train between KKDE and UMB, as it follows behind SEP.
