Passive control railway level crossings within the road network pose a significant safety issue, both for trains and multi-combination vehicles (MCVs) and restricted access vehicles (RAVs0. In order to have provision for the larger MCVs and RAVs, further testing and simulations were required to be performed on a range of characteristic heavy vehicle combinations.
Field testing of two new innovative vehicle combinations, a pocket road train and a B-triple, was carried out and the performance data collected was used to validate simulations. Simulated stopping distances, acceleration clearance times and sight distances are included in Section 3 for the list of subject (characteristic) vehicles on a range of grades, from a range of different initial vehicle speeds, for a range of train speeds. These results were compared with AS 1742.7 (2007).
