While other trains have odd numbers for the down train, Bhuj has got an even number. Hence thought there was a zone change.
Tue rake 1 departs from SHM to MAS and reaches back on Thu.
Thu rake 2 departs from SRC to MAQ and reaches back on Mon the next week.
Fri rake 1 departs from SRC to AII and reaches back on...
more... Tue the next week.
In the second week, rake 2 will become SHM MAS and SRC AII, while rake 1 will become Vivek.
The faulty one over here is SHM Bhuj which consumes almost an entire week for its to and fro journey.
