Transport Canada has implemented a number of new rules since Lac-Mégantic to require better securement of trains and rolling stock on track but we did see an increase in the number of uncontrolled movements so we believe that while those rules are a good step in the right direction, they're not enough to reduce the risk of an uncontrolled movement.
Most of them take place in yards where the risk is very low, but we still are concerned that the risk is there, particularly if these cars or trains get out on the main track.
