Low temperatures - Icing of switches - Broken rail - Frost heaves - Frost jacking of rock slope 3. High antecedent precipitation conditions contribute - Increased frequency of earth slides - Debris flows - Flooding - Scour erosion to bridges and embankments - Culverts failure 4. High wind - toppled empty double stake rail cars 5.Results - 9 Fatalities and ~100 injuries in last 38 years on CP Ways weather affects railways

Click on any symbol to select station and display data in “Station Data Display Area”. ] Map Panning Controls [ Click to pan map in any of the four directions for zoom levels beyond 100%. ] Map Surrounds flashes red when the SWAL level reaches alarm status for any station. Active Weather Warning List Area & Access Link. [ Click on any message to view details on given warning. Viewed warnings change color. Click and hold scroll controls to view long lists of messages. See “Display Options Menu” to also hide viewed warnings within list area. Note: Warnings are only updated when the Main Data Page is “Refreshed” (see Display Options Menu”. ] Display Options Menu Access Link [ Click on text to activate display options menu controlling: map layers, station filtering by SWAL status, station color assignment, display units, page refresh mode and, display of viewed warnings. Please refer to user guide for details. ] Station Database Selection Area [ Click on any one radial button to activate and display data of given database. Color of text and outline indicates highest SWAL status for each database. The outlines will disappear as the flashing alarm display is reset. Note: RED color indicates at or above critical conditions, YELLOW indicates approaching critical conditions and Black, within operational limits. ] Name of Active Station Database [ Caution: The presence of “FILTERED” in the database name indicates that the displayed SWAL status (color of the map symbols) IS POTENTIALLY NOT the highest SWAL status for any given station. Please see the setting of the “Associate station color with…” option on the “Display Options Menu” ] Map Zoom Factor Control [ Click and select zoom level. ] Station Data Display Area [ Click and hold scroll controls to view data for the selected station. Each data item is color-coded according its SWAL status. ] SWAL Flashing Surround Resets [ Click on “Current” or “Master” to stop the flashing (Indicates SWAL alarm) of the map surround for the active or, all databases. This action also deletes any colored database outline. ] Map Coverage & Panning Area [ For Zoom factors greater than 100%, a blue overlay shows the coverage and location of the main map. To relocate the main map, click and drag the blue overlay within the overview window. ] Report Generator Functions [ Alternatively click on map station symbols and the “Add Station” text to create a text report that can be “View”ed, “Print”ed and “Clear”ed ] Map Symbol Legend Access Link [ Click on text to view legend of map symbols and color coding assignment ] RailWIS – Rail Weather information system

Track side anemometer – NMC (Network Management Centre (= NASA Mission Control)) – Train crew 2. Track side anemometer – Train crew 3. Train mounted wind load pressure cell – Train crew

18. 2007/07/26 3 rd NSTWS - Canadian Pacific Page 18 of Anemometer measures wind speed and direction Anemometer sends message to NMC if thresholds are exceeded NMC analyses wind direction and speed and determines location of wind sensitive trains in area NMC directs wind sensitive trains to slow and stop in the nearest leeward siding Track side anemometers – NMC - train NMC Anemometer Trains
