Dynamics performance simulation of double-deck container flat car;

In light of the fact that the vertical vibration acceleration is on the high side on the loaded double-deck container flat car, on the basis of the test results from operation on track, the causes to the acceleration being on the high side are analyzed from the angle of resilient vibration of the cars.

The dynamic gauge analysis is made upon the double-deck passenger cars exported to Iran by CSR Sifang Locomotives & Rolling Stock Co.

Described are the structure, plane layout and equipment in the new type M6 double-deck passenger cars.

Described are the CORADIA double-deck passenger cars and X40 double-deck multiple units manufactured for Swedish State Railway by Alstom, as well as the concept of overall quality administration.

Double decked lanes are arranged in accordance with the unique formation of the shield tunnel and the required construction limit of highway, with proposals for double decked lanes in twin tunnels using DOT shield machines of equal and unequal diameters.

Briefly described are the main technical parameters,overall arrangement,carbody structure,equipments inside car,electric devices and structural characteristics of main parts and components on the double deck trailer cars.
