(remove the tracks) until six months after the Utility and Review Boards decision of the length of the discontinuance period on which the railway has to offer service to its customers. The boards decision was handed down January 15, 2015 and states that the railway must offer service (which can be trucks) until October 1, 2015. The earliest the railway can apply to abandon the line is April 1, 2016. Accidents The CBNS has experienced two significant derailments since taking over operation of the Truro - Sydney railway line from CN in 1993: On April 18, 2004, westbound freight train 301-18 derailed ten cars at mile 51.7 of the Hopewell Subdivision near Linacy at approximately 23h35 ADT. Nine of the ten derailed cars were loaded with liquified petroleum gas (propane). No individuals were injured, however, two schools and two residences were forced to evacuate for nine days while cleanup operations took place. The Transportation Safety Board of Canada investigated and determined that the train had been operated safely and that no mechanical defects existed in the locomotives or consist. The investigation determined that the derailment occurred as a result of a track issue; the slower freight train had been operating along a curve that was super-elevated. This type of track configuration dated to the high speed requirements of the Via Rail Canada "Dayliner" passenger trains which were canceled on January 15, 1990. The heavy weight of the slower freight train forced the lower track on the inside of the curve to collapse. On June 13, 2010, a westbound freight train derailed sixteen cars on the Hopewell Subdivision in Avondale Station. Six of the sixteen derailed cars were loaded with liquified petroleum gas (propane). No individuals were injured, however, several residences were forced to evacuate for multiple days while cleanup operations took place. The Transportation Safety Board of Canada is currently investigating. A CBNS official was quoted in local media as stating that a preliminary finding had determined that a defect in a non-CBNS freight car was thought to have caused the derailment. A subsequent minor derailment in Stellarton the following week where two freight cars left the tracks during a yard switching operation created a minor media sensation. The derailment coincided with a public debate in Nova Scotia about whether the provincial government would extend the five-year subsidy agreement that was tied to maintaining the Sydney Subdivision (eastern section of
