Abstract: Lnder the setting of sharp development of package quantity, the utilization of remaining capacity of
baggage ear in express transport was proposed. Based on the superiorities of railway passenger trains, such as
small operation time interval and wide coverage in territory, a kind of multidimensional 0-1 knapsack model was
established so as to solve the requirements of bulk cargo that are of multi-batches and limited quantities. Also
the greedy algorithm was designed based on the ' First Departure First Loading principle in order to more effec
tively use the remaining capacity of baggage car and dwell time. Lastly, an example was designed based on the
data of railway passenger trains departing form Lanzhou station along Longhai direction in one day, the outcome
explains thal the utilization of remaining capacity of baggage car in express Transport has the feasibility, necessity
and realistic significance
