The crew on train 303 were under the assumption that 113 had cleared based a clear signal at Ogden, and on conversations in the depots about 113. Train 113's departure was delayed for an outbound business train which 303 didn't know about. Link to full report: http://www.bst-tsb.gc.ca/eng/rapports-reports/rail/2016/r16c0065/r16c0065.html
