But i guess the biggest challenge with one rake of LHB will be the change in seating numbers to be done in the reservation system. The pre-defined quota for tatkal, RL, Pooled quota all will have to be redone. Of course if they dont do any thing it will still work as LHB will have more seats in any case. But yes rather than letting the rakes lie idle and getting spoilt it can be tried for one rake at least
