| Abstract: | The paper raises a constrained optimization method for deciding easement curve length in the raising operation speed of the existing railway. The method is used for the unmanageable condition that easement curve length and superelevation are limited, and so on. The paper also determines the maximum operation speed under these conditions. |

| Keywords: | existing railway raising operation speed easement curve constrained optimization |
