Practice has proved that the long-term, structural strength, "75" type of turnout and turnout mine stability measures to meet axle does not exceed 23t, through turnout rate does not exceed 80 ~ 100km / h safe operation of various types of rolling stock needs. Due to the low turnout this price, easy maintenance, parts interchangeability, and have been widely used in the field and other reasons, for quite a long time, "75" type of turnout will remain in China's railway traffic speed is low (not超过 80 ~ 100km / h) minor positive line and station lines and extensive use of dedicated lines. Mine turnout installed perpendicular to the track direction, due to the use of special low-profile cross-section tip rail turnouts coal specifications, eliminating the common rail tip 6mm vertical rail that irregularity than the basic track elevation, heart with wings frog rail section matching rail transition are more "75" type of turnout is more reasonable to ensure that high-speed driving when the longitudinal stability. Using special low-profile cross-section of the rail switch rail, which 60kg / m and 75kg / rn rail turnouts use 6OAT rail, 50kg / m rail turnout 50AT rail use.
