The BNSF tracks have slide problems in more places than just South Surrey. The North Delta escarpment is also prone to slides caused mostly by the vibrations from the trains. Houses shake, and cracks and fissures form in the yards along the route. The vibrations increase along with the number of trains, and that number is expected to more than double because the BNSF wants to twin the tracks along the river's edge to allow for even more train traffic.
Train safety records have not been "excellent" over this past year, as the longer and heavier trains have derailed many times recently. It's only a matter of time before a deadly slide occurs along our environmentally sensitive waterways, and the train companies are willing to play risk management. It's time to relocate the tracks away from our beaches and environmental reserves. Cost should not be the priority over public health and safety for the environment.
