0483/84, 04090/89 Jind Hisar, Hisar Delhi
How many 17 coach rakes are there for this pair of trains. If two dedicated rakes with maintenance at JIND, then very small time span for many maintenance.
And...
more... if JPR rake is attached with that of 54049/50, then there are many stations on Jind Panipat Rohtak route which could not occupy 17 coaches.
If possible then suggest RSA.
