The occupants are forced to work for 10 consecutive hours under such adverse environmental conditions.

The present invention has been made in view of the above circumstances, and can reduce the vibration and noise of the passenger compartment, improve the efficiency of air conditioning and heating, and significantly improve the crew's working environment. In terms of aspects, the objective is to provide a locomotive that is effective in flattening the work.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, a passenger compartment manufactured separately from a vehicle main body having an engine room is attached to the vehicle main body through an antivibration mount, and the passenger compartment is opened. It is equipped with a door that connects the passenger compartment and the engine room.

[0006]

[Action]

 According to this invention, the passenger compartment is manufactured separately from the vehicle main body having the engine room and is attached to the vehicle main body through the vibration isolation mount, so that the vibration of the passenger compartment is reduced. Also, since the passenger compartment and the engine room are separate bodies, each room wall is interposed between them, that is, two room walls in total, resulting in improved sound insulation and heat insulation between the two rooms. Therefore, the noise in the passenger compartment caused by the noise in the engine room can be reduced, and the effectiveness of cooling and heating in the passenger compartment is improved. Furthermore, in terms of production, the passenger compartment can be outfitted in a separate process from the main body of the vehicle in which the engine room is installed, so parallel work is also highly effective in leveling the work.
