Analysis of Derail over Small Radius Curves and its Prevention |
| |
| Abstract: | Based on analysis of three commonly\|seen derail cases over small radius curves, i.e., suspension, track damage and climb on rail, an introduction is given to three key elements concerning safety of train operation, that is the superelevation run\|off elevation, out\|of\|gauge, alignment level and its reverse phase composite unevenness. Countermeasures are put forward. |

| Keywords: | small radius curve derail causes countermeasure |
