| Abstract: | in view of the streamline locomotives with a certain ratio of thinness tolength moving in tunnels, the simplified formulas to estimate the friction loses along the wayand in partial areas have been established in this paper. Then, q convenient method to evaluate the aerodynamic drag of locomotives in tunnels is presented The new method can be consulted in the choice of locomotives and design of tunnels. |

| Keywords: | high-speed train tunnel ratio of thinness to length blockage ratio aerodynamic drag. |
