Study on the Calculation of Safe Sidetracking Time for the Local Train using Blocking Time Model

초록

It is increasing interested in the introduction of an express train to enhance the competitiveness of the railway. If the express train would be introduced in a certain line on which only local trains run, sidetrack is needed for the express train to overtake local train. In addition, it is also very important to properly set the sidetracking time of local train in terms of ensuring safety of rail traffic flows. This paper explains the calculation method of safety sidetracking time for the local train on the shunting station using the blocking rime model. And then, a case study shows the operation of the mixed train traffic using overnight-staying track of SMRT Line 6. It includes the estimation of safety sidetracking time for local train and the possible operation plan for the conflict-free local & express traffic flows.
