11010 Sinhagad Express & 12124 Decca Queen get delayed only because CST bound local trains.......!!
both Sinhagad & DQ has to trail Karjat - CST locals
11010 Sinhagad trails 7:54 Karjat- CST and trailing begins from Kalyan
some local trains that kept on waiting for 11010 are 8:45 Ambernath - CST F, 9:19 Thane - CST F and 8:41 Kalyan - CST...
more... (diverting on fast line at Thane 9:13)
If 11010 get delayed before Karjat then it has to trail one of the above mentioned locals
Now talking about DQ
12124 DQ has to trail only 8:27 Karjat CST and trailing starts from Vikhroli/Ghatkopar
No local trains are scheduled by CR in the 20-25 mins. time period which is expected time period of DQ to cross KYN/TNA
