Meanwhile, the problems of insufficient station number, small scale, insufficient loading and unloading capacity and the like of the railway container exist. More importantly, in the freight platform after electrification transformation, because the electric traction system contacts with a power grid (a contact network or a high-voltage line), a large number of platforms do not have the capacity of directly loading and unloading heavy-load containers. The overhead contact system is generally arranged below the off-rail height of 6.5 meters, and conventional loading and unloading equipment such as a container reach stacker and a gantry crane, which need to occupy the space above the vehicle, cannot be actually operated. If a container handling station needs to be opened, only the internal combustion locomotive can be applied to detach the contact power grid or change the route to be dragged to a special goods yard by using the internal combustion locomotive, and the defects of long construction period, large investment waste, high operation cost, more harm of ring and the like exist.
