Railway Occurrences in 2010

Accidents

Overview of Accidents and Casualties (Tables 1 to 3 - Appendix A)

In 2010, 1,076 rail accidents1 were reported to the TSB (Figure 1), a 3% decrease from the 2009 total of 1,043 but a 16% decrease from the 2005-2009 average of 1,278.

Figure 1 - Rail Accidents, 2001-2010 [D]

Figure 1 - Rail Accidents, 2001-2010

Freight trains accounted for 69% of all trains involved in rail accidents in 2010, followed by single cars/cuts of cars and Track units in proportions of 10% and 5% respectively.

The largest proportion of reported rail accidents are non-main-track related. In 2010, these accounted for more than half of the total (Figure 2). Typically, most non-main-track accidents are minor, occurring during switching operations at speeds of less than 10 mph.

Main-track derailments and collisions accounted for 8% of all accidents in 2010, up from 7% in the previous year.

In 2010, 17% of rail accidents involved vehicles or pedestrians at highway-rail crossings, nearly unchanged from 18% over the previous five years.

Figure 2 - Rail Accidents by Type, 2010 [D]

Figure 2 - Rail Accidents by Type, 2010

In 2010, 141 accidents involved dangerous goods (either rail cars or road vehicles carrying or having recently carried dangerous goods), up from the 2009 total of 133, but down from the five-year average of 175. Of these, 81% were non-main-track accidents. Two accidents resulted in a dangerous goods release, down one from the 2009 total, and down from the five-year average of four.

Rail fatalities totalled 81 in 2010, up from 71 in 2009 but down from the five-year average of 85. Of the rail fatalities, trespasser2 fatalities was the largest fatality category with 55 in 2010, similar to the five-year average of 56 (Figure 3). Crossing fatalities totalled 24 in 2010, up from the 2009 total of 19, but down 11% from the five-year average of 27. In 2010, one employee was fatally injured, down from the five-year average of two.

A total of 62 serious injuries resulted from rail occurrences in 2010 (Figure 4), up from 50 in 2009 but down from the five-year average of 64. Trespasser injuries totalled 19 in 2010, up 19% from the 2009 total of 16 but down 14% from the five-year average of 22. Crossing accidents3 resulted in 28 injuries, up from 21 in 2009 but down from the five-year average of 32. The remaining 15 injuries occurred in other types of accidents

Accidents by Type (Tables 4a to 9)

Main-track accidents (Tables 4a and 4b): The number of main-track accidents (accidents other than crossing and trespasser accidents which occur on main-track or spurs) totaled 161 in 2010 (Figure 5), down from 169 in 2009 and from the five-year average of 219. Rail activity on main-track increased by 7%4 from the previous year, and the main-track accident rate decreased 9%, from 2.3 main-track accidents per million main-track train-miles in 2009 to 2.1 in 2010.

Figure 5 - Main-Track Accidents and Accident Rates, 2001-2010 [D]

Figure 5 - Main-Track Accidents and Accident Rates, 2001-2010

Main-track collisions and derailments are the most serious categories of rail accidents in terms of potential risk to the public and financial loss (e.g., when passenger trains are involved or dangerous goods are released from trains that derail while travelling at high speeds in populated areas).

There were four main-track collisions in 2010, down one from the 2009 total (Table 1) and down from the five-year average of six. No fatalities or serious injuries resulted from main-track collisions in 2010, and none resulted in the release of dangerous goods.

A total of 80 main-track derailments were reported in 2010, a 19% increase from the 2009 total of 67 but a 42% decrease from the five-year average of 139 (Figure 6). The number of main-track derailments per million main-track train-miles increased to 1.03 in 2010 compared to 0.93 recorded in 2009 but decreased from the five-year average of 1.68.

Figure 6 - Main-Track Collisions and Derailments, 2001-2010 [D]

Figure 6 - Main-Track Collisions and Derailments, 2001-2010

One fatality and eight serious injuries resulted from main-track derailments in 2010.

In 2010, 13 main-track derailments involved dangerous goods, up from 11 in 2009 but down from the five year average of 24. One of these resulted in a release of dangerous goods.

In 2010, 32% of assigned factors5 for main-track derailments were equipment-related, compared to 31% in 2009 and the five-year average of 33%. Track-related represents 35% of assigned factors in 2010, compared to 39% in 2009 and 37% for the five-year average.

Non-main-track accidents (Tables 5a to 6b): Non-main-track collisions totalled 94 in 2010, down from 95 in 2009 (Figure 7) and down from the five-year average of 99. Derailments occurred in 46% of non-maintrack collisions, and 70% of these non-main-track collisions involved the derailment of one or two cars.

Figure 7 - Non-Main-Track Collisions and Derailments, 2001-2010 [D]

figure 7 - Non-Main-Track Collisions and  Derailments, 2001-2010

No fatalities or serious injuries resulted from non-main-track collisions in 2010.

Dangerous goods were involved in 28% of non-main-track collisions, none of which resulted in a release of product.

Factors assigned to non-main-track collisions are mostly rules-related (86%) (e.g., non-compliance with prescribed procedures). Failure to protect, such as improper positioning of movements and handling of switches, was assigned most often as a factor.

There were 540 non-main-track derailments in 2010 (Figure 7), up 9% from last year but down 15% from the five-year average of 632. In 80% of these accidents, one or two cars derailed.

No fatalities or serious injuries resulted from non-main-track derailments in 2010. Dangerous goods cars were involved in 16% of non-main-track derailments, and one resulted in a release of dangerous goods.

In 2010, there was a 20% decrease in track-related factors assigned to non-main-track derailments compared to the five-year average, as well as a 7% decrease in rules-related factors (e.g., non-compliance with prescribed procedures). Factors assigned in an accident are considered to have acted in combination to contribute to the occurrence.

Crossing accidents (Tables 7 and 8): Crossing accidents represent one of the most serious types of rail accidents in terms of casualties; in 2010, 22% resulted in either serious or fatal injuries. Although crossing accidents do not usually result in substantial damage to railway property or equipment, the motor vehicles involved are usually heavily damaged or destroyed.

There were 181 crossing accidents in 2010, down from 188 recorded in 2009 and down from the five-year average of 228. Accidents at public automated crossings (88) decreased 13% from the 2009 total of 101 and decreased 27% from the five-year average of 120. Accidents at public passive crossings (67) increased 20% from the 2009 total of 56. Accidents at private crossings decreased 31% from the five-year average of 35. The proportion of crossing accidents that occurred at public automated crossings decreased from 54% in 2009 to 49% in 2010 (Figure 8). Although there are nearly twice as many public passive crossings as public automated ones, the higher number of accidents occurring at automated crossings is due, in part, to higher vehicle and train traffic volumes at these crossings.

Figure 8 - Crossing Accidents by Type of Crossing, 2010 [D]

Figure 8 - Crossing Accidents by Type of Crossing, 2010

There were 19 fatal crossing accidents in 2010, up from 17 in 2009 but down from the five-year average of 24. Although crossing accidents involving pedestrians accounted for only 8% of crossing accidents in 2010, they accounted for 42% of fatal crossing accidents. Crossing-related fatalities totaled 24 in 2010, an increase from 19 in 2009 but a decrease of 11% from the five-year average of 27.

In 2010, 3 crossing accidents resulted in derailments, down from the 2009 total of 6 and down from the five year average of 7. Heavy vehicles (e.g., dump trucks, tractor trailers) were involved in 14% of crossing accidents in 2010; however, they accounted for all of those resulting in a derailment.

Crossing accidents in Quebec, Ontario, Alberta and British Columbia were at least 20% lower than their respective five-year averages (Figure 9), while accidents in other provinces were close to their last five-year averages.

Figure 9 - Crossing Accidents by Province

Trespasser accidents (Table 9): Trespasser accidents involve persons, primarily pedestrians, not authorized to be on railway rights-of-way and who are struck by rolling stock other than at railway crossings. They totaled 81 in 2010, up from the 2009 total of 72 but down from the five-year average of 84.

In 2010, Ontario accounted for 43% of trespasser accidents with a total of 35, British Columbia accounted for 21%, and Quebec accounted for 16% of all trespasser accidents.

In 2010, the proportion of trespasser accidents that were fatal (65%) was similar to the five-year average of 66%. In addition, the proportion of trespasser accidents resulting in serious injuries (23%) was lower than the five-year average of 25%.

Incidents

Overview of Incidents (Tables 10 and 11)

In 2010, there were 159 reported rail incidents, down from 207 in 2009 and down from the five-year average of 222.

Figure 11 - Rail Incidents, 2001-2010 [D]

Figure 11 - Rail Incidents, 2001-2010

A dangerous goods (DG) leaker incident involves the unintentional release of a hazardous material while in transit and does not involve an accident. The vast majority of these incidents involve small quantities of products. The reported DG leaker incidents totaled 40 in 2010, which is a 49% decrease from the 2009 total of 78 and a 54% decrease from the five-year average of 87. In 2001, DG leaker incidents represented 59% of all incidents. In 2010, DG leaker incidents accounted for 25% of reported rail incidents. (Figure 12).

In 2010, there were 102 incidents where the movement exceeded the limit of authority6, compared to 106 in 2009 and the five-year average of 103.

  1. Federally regulated railway occurrences.
    TSB does not investigate all occurrences; therefore, assigned factors may not represent TSB findings.
    Occurrences are normally only reported to TSB with one assigned factor. The TSB may assign additional factors.
  2. Some factors are assigned by highest category (e.g. Equipment or Track), therefore the breakdowns may not sum up to the category total.

Appendix B – Definitions and Explanatory Notes

Definitions

The following definitions apply to railway occurrences that are required to be reported pursuant to the Canadian Transportation Accident Investigation and Safety Board Act and the associated regulations.

Railway Occurrence

  1. Any accident or incident associated with the operation of rolling stock on a railway, and
  2. Any situation or condition that the Board has reasonable grounds to believe could, if left unattended, induce an accident or incident described in paragraph (a) above.

Reportable railway accident

An accident resulting directly from the operation of rolling stock, where:

  1. a person sustains a serious injury or is killed as a result of:
    1. being on board or getting off the rolling stock, or
    2. coming into contact with any part of the rolling stock or its contents, or
  2. the rolling stock:
    1. is involved in a grade-crossing collision,
    2. is involved in a collision or derailment and is carrying passengers,
    3. is involved in a collision or derailment and is carrying dangerous goods, or is known to have last contained dangerous goods the residue of which has not been purged from the rolling stock,
    4. sustains damage that affects its safe operation, or
    5. causes or sustains a fire or explosion, or causes damage to the railway, that poses a threat to the safety of any person, property or the environment.

Reportable railway incident

An incident resulting directly from the operation of rolling stock, where:

  1. a risk of collision occurs;
  2. an unprotected main track switch is left in an abnormal position;
  3. a railway signal displays a less restrictive indication than that required for the intended movement of rolling stock;
  4. an unprotected overlap of operating authorities occurs;
  5. a movement of rolling stock exceeds the limits of its authority;
  6. there is runaway rolling stock;
  7. any crew member whose duties are directly related to the safe operation of the rolling stock is unable to perform the crew member's duties as a result of a physical incapacitation that poses a threat to the safety of any person, property or the environment; or
  8. any dangerous goods are released on board or from the rolling stock.

Serious Injury

An injury that is likely to require admission to a hospital.

Dangerous Goods Involvement

An accident is considered to have dangerous goods involvement if any car in the consist carrying (or having last contained) a dangerous good derails, strikes or is struck by any other rolling stock or object. It does not mean that there was any release of any product. Also included are crossing accidents in which the motor vehicle involved (e.g. tanker truck) is carrying a dangerous good.

Explanatory Notes

Accidents by Railway

Accident totals are not presented by railway. The track, train and personnel in an occurrence may all belong to different companies; also an occurrence may have several contributing factors. Presenting data based purely on one of these criteria or factors would be misleading, and misinterpretation of data by readers could unfairly affect a company's competitive position.


  1. Refer to Appendix B for a definition of a reportable railway accident.
  2. Trespasser accidents involve persons, primarily pedestrians, not authorized to be on railway rights-of-way and who are struck by rolling stock other than at railway crossings.
  3. A crossing accident is when a railway rolling stock is involved in a grade-crossing collision with a motor vehicle or pedestrian, resulting in death, serious injury or property damage.
  4. As provided to TSB by the Strategic Information Branch of Transport Canada.
  5. Occurrences are normally only reported to TSB with one assigned factor. Since multiple factors can contribute to an occurrence, the TSB may assign additional factors to an occurrence.
  6. Movement exceeds limits of authority is when a train or track unit movement occupies a main track (including signalled sidings, signalled yard tracks and station tracks) or portion thereof without the required authorization.
