Subject: Rail Safety Advisory Letter – 617-02/19: Securement of cars that are considered “attended” during yard switching operations
On 04 December 2018, at about 0825 Atlantic Standard Time, a Canadian National Railway Company (CN) yard assignment (assignment) was switching cars at Edmundston Yard in Edmundston, New Brunswick. The assignment crew consisted of a locomotive engineer, a conductor and a conductor trainee (trainee). During switching operations, 2 cars that had been placed on track EA14 (west-end yard lead) started to roll uncontrolled back towards the assignment, resulting in a collision with the assignment’s trailing locomotive (Figure 1). The trainee, who was standing on the side ladder of the trailing locomotive, sustained fatal injuries (TSB Occurrence No. R18M0037).
The 2 cars had been placed on the west-end yard lead near the Track 5 switch. As per normal practice at this yard, the crew had left the cars with emergency brakes applied before continuing the work. After uncoupling from the 2 cars, the assignment (now consisting of 2 locomotives only) proceeded westward for about 200 feet, just passed the Track 4 switch. The trainee then lined the Track 4 switch to allow the assignment to reverse eastward into this track. Upon re-boarding the trailing locomotive, the trainee was positioned on the northeast ladder, next to the locomotive platform where the conductor (who was coaching him) was positioned. The trainee then instructed the locomotive engineer to back up 20 car lengths in order to pick up a car positioned further east on Track 4.
Shortly after the assignment began reversing towards Track 4, the conductor noticed that the 2 cars on the west-end yard lead were rolling uncontrolled towards them. The conductor immediately instructed the locomotive engineer to stop the assignment, and attempted to warn the trainee. The assignment was placed into emergency, but was not able to stop before side-colliding at about 9 mph with the uncontrolled cars. The trainee, who was still positioned on the ladder of the trailing locomotive, sustained fatal injuries.
During yard switching operations, cars that are set off are considered to be “attended” if the crews are continuing their work in the vicinity of the cars. As such, when these cars are set off on a track in Edmundston Yard, they are typically secured with air brakes only.Footnote 1
Canadian Rail Operating Rules (CROR) Rule 112 states (in part):
Equipment is considered unattended when an employee is not in close enough proximity to take effective action to stop the equipment should it move unintentionally.
The rule implies that an employee in the “proximity” would be able to intervene effectively to stop an unintentional movement of the equipment. However, as in this occurrence, employees are normally engaged in other work activities and may not always be able to take effective action to stop the equipment, should it move unintentionally. Furthermore, if equipment does roll unintentionally, the crew members may have to climb onto the moving equipment to take action, placing them in a hazardous situation.
In 2016, the TSB investigated a similar occurrence involving an uncontrolled movement at the Co-op Refinery Complex in Regina, Saskatchewan (TSB Occurrence No. R16W0059). In that occurrence, tank car GATX 67963 (loaded with asphalt) had been secured only with an emergency brake application. The tank car was considered to be “attended,” as the crew was continuing its work in the general vicinity. About 10 minutes later, the tank car rolled away uncontrolled. The crew was unable to take effective action to stop it before it exited the yard.
In 2018, there were 16 TSB-reportable occurrences (including this occurrence) involving cars that had been left in the yard and considered “attended,” which then rolled unintentionally and resulted in a collision or derailment (Annex A). In each of these occurrences, while the cars were considered to be “attended,” the crew members were not able to take effective action to stop the uncontrolled movement. As written, CROR Rule 112 may not be sufficiently clear with respect to when cars can be considered as being “attended.” Given the risks associated with cars rolling unintentionally, Transport Canada may wish to review, clarify and update the definition of “unattended” as it pertains to CROR Rule 112 to ensure that this rule is appropriately (and consistently) applied during yard switching operations.

| Occurrence | Date | Subdivision | Mile | Occurrence Summary |
|---|---|---|---|---|
| R18V0009 | 2018-01-12 | Yale | 112.7 | The Canadian National Railway Company (CN) east lead assignment with locomotive CN 7279 had cars listed for track PF30. By mistake, the crew shoved past track PF30, towards track PF31, and stopped just short of going onto track PF31. At the same time, the conductor decided to remove the hand brake in track PF30 and allowed the cars to roll towards the movement. The cars rolled foul of the lead (at the east end), resulting in car CN 412224 colliding with car WC 22176 as the crew began pulling back to clear the PF30 switch. Car CN 412224 was pulled eastward, derailing the A-end set of trucks. The safety appliances on car WC 22176 sustained damage. There were no injuries and no dangerous goods were involved. |
| R18E0010 | 2018-01-14 | Slave Lake | 154.1 | A CN train crew, while preparing to lift cars from track HA10, applied hand brakes on the south end and released the hand brakes on the north end when the cars began to roll northward, striking the derail and derailing car AEX 19628 (1 set of trucks on the A-end). There were no injuries and no dangerous goods were involved. |

Rail car NCIX 173 (loaded covered hopper car) rolled out of track OR16 and struck car NCIX 6826, which was stopped on the lead coming out of track OR17. Car NCIX 173 derailed upright, with one axle on the A-end on the ground. There were no injuries and no dangerous goods were involved. |
| R18E0060 | 2018-04-08 | Wainwright | 263.9 | A CN Walker Yard assignment at the east end of track CF74 shoved single car AEX 20057 onto track CF74 and made a light engine move onto track CF78. Upon exiting track CF78, locomotive CN 7504 sideswiped car AEX 20057 that had rolled uncontrolled eastward out of track CF74, causing car AEX 20057 to derail on its side.
