BG LHB AC Hot Buffet Car --- Earler these cars can be seen along with high profile train services like Rajdhani, Duronto etc. But due to Indian railways' massive LHBfication drive in recent times, these coaches are slowly being inducted in regular express sevices as well. These are standard air-conditioned cars with dedicated pantry & kitchen units & equipments along with standard modern facilities, but no passenger accommodations except for the catering people. Developed by latest German LHB (Linke Holfmann Busch) technology (later taken over by Alstom in 1998). They are considered to be "anti-telescopic", which means they do not get turned over each other, if the train derails or gets involved in a collision. Type - LWACCB.
