Extension venam , RSA venam. If CR thinks and make 12133 to depart CST around 20:00 pm instead of 22:00 somehow and make it to arrive Goa at 05:10 and MAJN at 10:50 am , the return can easily leave the MAJN around 13:50 on time almost all of the day . Its the simple and easy solution. It dont need RSA , no other zone permission no extra rakes.
