According to the experience, when the turnout shakes, there will generally be reverse composite irregularities, structural triangular pits and directions between the turnout structure and the lines on both sides! This depends on the position of your switch and the line conditions on both sides! Make the front and rear 100M of the roadside level on the same side, and make the dimensions of slope and gauge change rate. In addition, there are hanging plates, which will be found in many turnouts and will melt soon in spring. Pay more attention!
