Paschim can't run with LHB until the slip coaches to KLK are removed....Till now the LHB coaches can't carry slip portion as they are not self generating and have to run with EOG on both ends or a HOG enabled loco...If a slip portion is attached then it can't be separated from the main train as the coaches must be between the two EOGs....And it's Quite difficult to remove an EOG from the back of the rake and attach it again.....
