The Lanxin Railway is an important part of the road and bridge corridor, and it is also one of the main routes for the China-Europe train. Jiayuguan Station is the largest passenger and freight marshalling station in Hexi, Gansu Province, with the rapid growth of freight volume of the Lanxin Line, the utilization rate of Jiayuguan Station to the departure line has tended to be saturated, which has become a blocking point and pain point that restricts the large capacity of the Lanxin Trunk Line.
After the completion of this transformation, Jiayuguan Station is still used as a section station and a general speed passenger station, mainly handling technical operations such as the arrival and departure of ordinary speed passenger cars, the decompilation of freight cars, and the replacement of locomotivesThe Dacaotan direct field mainly handles the technical operations of trains without decompilation and replacement. It can greatly improve the overall freight capacity of the Lanxin Line and solve the problem of cross-interference between passengers and goods.
