11013 timings are also dependent on arrival of 11014 at Kurla. Moreover the biggest issue is the run from DMM till SBC. Since it is just a pass through train SWR does not give it priority. Once the new terminal at BYPL opens it will not even enter BNC, SBC so maybe might have a much earlier arrival in CBE.
Attached is the reply i got from SWR some months back on the heavy trolling between DMM-SBC stretch
