Yes, doubled the quota but all zones have planned in their way. Some put all the LBs in the first coaches from the loco, some earmark particular number of berths across all coaches.
.
In my opinion 1 4, 9 12, 57 60, 65 68, (73 76 LHB SL) should be earmarked for SS so the pax can easily access the door and the Washroom.
