However, due to the fact that land and bridge transportation requires customs clearance and transit in many countries, and the standards in Europe and Asia are not consistent, the advantages of land and bridge transportation have been greatly weakened. Usually, the time for a train to pass the customs inspection and stop is about 24 hours, and then the relevant customs clearance and transit formalities will take a day or even longer. Inconsistency in the standards of Asian and European railway tracks has also led to an increase in cargo handling procedures and reduced transport efficiency. All these factors also restrict the development of land bridge transportation.

To solve the problem of the continental bridge, we must rely on the improvement and simplification of relevant laws in our country to simplify the process of customs declaration and transit. We can adopt the method of declare in advance, and do not have to wait until the train arrives. According to the declaration time in declare in advance, we can reduce the stay time and inspection time of the train at the gateway.

For the case that the railway standards in Asia and Europe are not consistent, the whole carriage can be directly and parallelly transferred. After entering the transfer station, the trains can stop in parallel next to the corresponding train for exchanging goods, and the carriages can be one-to-one corresponding to each other, and the corresponding stops can be completed to start the translation replacement of the whole carriage. Such replacement greatly shortens the loading and unloading transfer time and does not disturb the corresponding order of goods arrangement. This method is technically feasible, but it has not yet been applied to the actual operation. I believe this method will eventually be put into practice under the constant development.
