Short Content: 1 outline 　　In the subway engineering construction, the project (i.e. machine shop truck) played the very vital role with the diesel locomotive. Especially in subway construction initial period, because needs to ship the massive building material, but the initial period transportation condition is also quite crude, thus the machine shop truck becomes the main transport means. After the subway completes in the operation, the machine shop truck may shoulder in the vehicles section similarly switching cars and ships under the ...
