The paper explores the following respects. First of all, to introduce the classification and technical equipment of the marshalling yard. It analyzes the tenser current situation and existing problems of several marshalling yards in our country and proposes the direction of strengthening the adaptation ability. Secondly, to analyze the location and the role in the network of lanzhou west station. It computes the adaptation ability to lanzhou west, establishes a queuing model about the ability of the hump disintegration, calculates and analyzes the units disintegration capacity of the hump about lanzhou west station under the restrictions of the number of shares S and the allowed value of T of average time that a train reached the market. Finally, to analyze the affecting factors of lanzhou west station’s adaptation ability, and make the appropriate solution. This article is focused on the affecting factors of lanzhou west station’s adaptation ability ,which is classified and analyzed. It takes use of AHP method to analyze each affecting factors, determines the size of impact that vari
