Abstract
As comparing to plain track, turnouts are under severe condition such as impact wheel loads and so on, the number of sleepers designed in turnout is larger than that in plain track in the same interval. But no design standards has been made according to decide the pitch of sleepers in turnout. In this study, the rail deflections and steel sleeper, the limited beam model on the elastic support theory evaluated stresses of this turnout. Using the turnouts designed by this way and constructed in railway yards the deflections and stresses were measured under condition of a running locomotive. The results were within allowable limits and it was confirmed the improved turnout could be used in operating lines.
