I once thought of idea. if only we could get rid of AC CC in 22405/06 they could manage some RSA with rakes of Gaya, BGP,JYG GR to avoid reschedule. For instance 22406 on Monday. Gaya GR 22409 rake of Monday could depart as 12570 on Tuesday while 12569 rake could depart rt as 22406 on Wednesday. Even if 22405 on Wednesday is late by say 6 hours it still has 7 hours of Primary maintenace time to depart as 12212 on 9pm.
