more... of rake and 59395 Betul Chhindwara Passenger continues till CWA from where the train becomes 59386 Penchvalley passenger. The slip now continues its journey till Amla PF1 where it is detached and sent to siding beside PF3, after some time 18237 Chattisgarh express arrives Amla and the slip gets attached in the front of it(Amritsar end) and continues journey till Amritsar.
In Return the 18238 Chattisgarh express brings the coach till Amla, its detached(from ASR end hence the halt time is less) and attached with 59385 Penchvalley Passenger and continues journey with it till Chhindwara and with 59396 CWA BZU pass till Betul, when the Passenger arrives Betul the slip is detached again and attached after 51254 Chhindwara Amla Passenger arrives and becomes 51294 Amla Nagpur Passenger, the coach then continues for till Nagpur for Primary Maintenance, the coaches are rotated with other trains of Nagpur Base(e.g. Sewagram express, Prerana express).
The reason being absence of Primary Maintenance at Chhindwara(might come up in future after Nagpur Chhindwara completes). The coach is running post introduction of Chattisgarh express,and after extension of Penchvalley fast passenger to Chhindwara, 7 trains carry this coach in the cycle.
