Moreover on Fri there is a special congestion in KNE. 12520,19710,12042, 15942 & 75744 arrive KNE one after the other, but 15715 originate from KNE & for that there is no additional PF is available. Today 15715 departed @7.20 i.e.80 mts behind schedule. As long as this train remains on PF2 all the above Dn trains are taken on PF1 which is a Up PF. So a series of Up trains which all halt @KNE has to wait at outer unless the Dn train vacates the PF. Making things worst, TRT machine work, deep screening of ballast & ballast cleansing work is going in KNE PJP Up main line for which 50 kmph TSR applied since last 45 days. & block taken for 4 hrs everyday after giving passage to 75719.
