  1. Unit 7Railroad Equipment Records

  2. Objectives • Student will identify the various types of records associated with railroad operations that relate to the fire investigation. • Student will describe how to interpreting each type of record. • Student will describe why time is of the essence in obtaining railroad records.

  3. Event recorder printouts Hot box detector activation records Dragging equipment detector records Dispatch records Radio records from dispatcher Operational period train warrants Mechanical repair and inspection records Internal policy and procedure manuals Consist manifests Statements from crew Railroad timetables System map Track profiles Conductor’s log Specialized Investigative Records

  4. Initial attack protocol Do the locomotive (s) have event recorder (s)? Yes No Obtain event recorder printout from each locomotive ASAP Get crew and witness statements Get crew and witness statements

  5. Investigation protocol Do the locomotive (s) have event recorder (s)? No Yes Obtain event recorder printout from each locomotive ASAP Get crew and witness statements. • Railroad Dispatch records • Radio • Hotbox detector activation • Dragging equipment activation • Railroad records • Operational period warrants • Consist manifests • Mechanical records • Railroad specific documents • Railroad time table • Track profile • System map • Policies and procedures

  11. Event Recorder Printout

  12. Train crew interviews • Conductor and/or Engineer - Did the crews on any trains you passed or met mention anything about your train ? • Engineer - How were you handling the train, power, dynamic brake, combination power and air brakes? Was there sufficient power to operate the train ? • Conductor and/or Engineer - Did the crew that brought this train into your terminal say anything about activations or trouble with the train ?

  13. Train crew statement “I went back to isolate the engine from the other two and saw flames and sparks coming from a small hole in one of the dynamic brake cooling grids, as well as hot molten metal surrounding the hole. When I isolated the engine, the flames, smoke and melting ceased.”

  14. Dispatch and initial report of fire records Written or recorded • Conversations between train crews and dispatchers. • Reports to police, fire, or other public agencies. • Reports to local news media. • Initial attack size up, report of conditions, requests for resources. • List of reporting parties to include phone numbers, addresses and other pertinent information.

  15. Hot box detectorDragging equipment detector Hotbox and dragging equipment notifies the train of: • Milepost number • Total axle count • Suspected axle number • Time of notification

  16. More on detectors… • Some detectors may report both dragging equipment and hot axles or journal boxes or spikes in the temperature. • Procedures for dealing with hot box activation on concrete ties is different than wood. • May or may not detect a stuck brake or set brake. • Dragging equipment detector has paddles set below track level that are struck by whatever is dragging.

  17. Crew records • Conductor’s log is usually retained for five trips. • General orders tell the conductor what has to be recorded and the format to use.

  18. Train operation records • Track warrants for the train or trains involved • Train consist manifests • Mechanical records

  19. Consist line up

  20. Locomotive maintenance record

  21. General railroad specific documents • Time tables • System maps • Track profile maps • Internal policies and procedures

  22. Fire agency documents • Inspection notices • Past correspondence relating to enforcement of area laws • Past fire history documentation

  23. Summary • The various types of records associated with railroad operations that relate to the fire investigation have been discussed. • The investigator should seek outside experts to interpret some of the more complex records. • Time is of the essence in obtaining these railroad records.

  24. Question 1 Event recorder printouts are kept indefinitely by the railroad. True Incorrect

  25. Question 2 Dragging equipment detectors produce a print out daily. • True • False

  26. Question 3 Track profile map can be used to identify: • Milepost • Grade profiles • Elevation • All of the above • None of the above
