RAILWAY CONNECTION FOR A HIGH-SPEED CIRCULATION ON A DEVIEEWAY, AND FIXED-POINT FIXED CROSSING HEART

摘要

The invention relates mainly to a railroad connection connecting a straight main track to a curved deflected track and is essentially characterized in that the variable curvature portion (5) of the branch (1) comprises a fixed point crossover core (6) for which the length (L3) is less than or equal to 11.8 meters, the distance between the running treads (F1) at the input of the core (6) is greater than or equal to 82 millimeters, the distance between the treads (F2) at the output of the core (6) is greater than or equal to 258 millimeters, and the angle α at the theoretical peak (9) is between 1.7 and 1.96 grade, and in that the radius R of the fixed curvature portion (4) of the branch (1) is 3000 meters, the length (L1) of the fixed curvature portion (4) is 60 to 70 meters, and the length (L2) of the portion to variable curvature (5) is between 44 and 53 meters. The invention further relates to a fixed tip crossover heart for making such a connection.
