Basically this is a single Bokaro-Bardhaman train which runs in 2 part as Bokaro-Asansol and Asansol-Bardhman as MEMU are not allowed to run for more than 250km at a go
Similarly there are Bardhaman - Jhajha memu, bardhaman - Gomoh memu, Bardhaman - Purulia memu, Bardhaman - Jasidih memu which runs as 2 separate MEMU
