This train has LHB Coaches consisting of 52 berths per every 2AC Coach.
In trains having ICF Coaches (Just like this train had in the earlier years), the total number of berths were till 46.
Hence the last 4 berths were placed as:
42-LB, 43-UB, 44-SLB, 45-SUB. (In some trains 44 was also found to be LB bang opposite to 42 in the same...
more... compartment) while 46 existed as SLB in the opposite bay.

In the LHB Avatar, the regular arrangement is not broken at 46, but is done right in the next compartment where 49 is placed as LB, 50 as UB, 51 as SLB and 52 as SUB.
