Background

Freight traffic for rail transit is not a fresh concept, and at present, the operation modes of subway freight can be classified into 3 types: the 'passenger-cargo mixed loading' mode claims that small cargo hold units are placed in passenger cabins, and a car escort person manually unloads the cargo hold during stop of a subway train, generally does not change the original structure and the driving plan of the rail transit train, and is easy to realize, low in manufacturing cost, low in transportation capacity and not obvious in scale economic effect. The collinear pulling and separating are required to update the layout of subway stations and the grouping and operation of trains, and logistics equipment is required to be equipped in the stations to carry out operations such as loading and unloading of cargo hold units of independent carriages, automatic sorting, middle-dedicated warehouse and the like. The collinear pulling mode adopts the mode of adding an extra freight carriage at the tail end of the train, so that passengers can get on and off and cargo loading and unloading can be completed synchronously. The collinearly separating mode adopts independent freight and passenger trains to operate in a collinearly shift mode, and separates the passenger and freight transportation by stopping at different platforms.

However, the passenger-cargo mixed-loading subway freight mode of the conventional rail delivery system cannot form scale effect, and only small articles can be transported, and the collinear-pulling subway freight mode requires frequent grouping and unhooking operations of subway vehicles, so that the time consumption is long, and the collinear-pulling subway freight mode requires independent freight by providing logistics equipment in a station, so that the cost is high. Therefore, it is desirable to provide a passenger-cargo sharing subway car system that can be quickly serviced to achieve a quick conversion between passenger-freight cars, so as to reduce the influence of the co-linear trailing grouping and unhooking operations and increase the flexibility of subway transport capacity.
