Spotted the rake from howrah side to ckp side:
SLR, S4, S3, S2, S1, SK1, B1, BK1, A1, D1, SLR.
Don't know why it's K added, in case of extra coach E is added, may be S5 and B2 onwards are with BKSC portion, and those reservations are done for next 4 months. So can't rename them now.
In case of slip...
more... trains they add T for Tata, K for Koraput, but K for CKP portion is interesting.
