Which type of line blockage or possession was involved? What were the weather conditions at the time and location of the incident? Station Track or trackside Level Crossing Tunnel Yard/Depot/Siding Entering a possession Exiting a possession Within a possession None of the above T-COD Disconnection Handsignaller Emergency protection Not in possession Token/block indicator Bright sunlight Dull/Overcast Fair/Fine Rain Falling snow Freezing Frost High wind Mist Thick fog 1.11 Was the visibility at the time and location of the incident More than 200 yards? Less than 200 yards? 1.12 Was frost present? 1.13 Was the site inspected? Page 1 of 10

2 PART 2 SUMMARY OF THE INCIDENT Please use this space to record a brief description of the SPAD incident. The information written here will be entered into SMIS: Page 2 of 10

3 PART 3 SPAD details 3.1 What was the length of overrun? (In metres or yards) 3.2 Did the SPAD occur on a running line? Was the route set from a siding onto a 3.3 running line? Did the train proceed beyond or obstruct 3.4 the fouling point? Was the aspect displayed in sufficient time 3.5 for it to be possible for the driver to stop? Was the line protected by Automatic Train 3.6 Protection (ATP)? 3.7 Was the ATP fully operational? 3.8 Had the ATP been isolated /over-ridden by the driver? (Note : Information to support the answer to this question may be in form RT/3119/B section 4.8) Was the clearing point of a home signal 3.9 exceeded? 3.10 Were there any points run through? Was a braking problem a possible factor of 3.11 the incident? Was low railhead adhesion a possible 3.12 factor of the incident? Was there any damage caused to the 3.13 infrastructure or to the rolling stock? Were there any injuries, excluding traumatic 3.14 shock? 3.15 If 'Yes' to 3.14, were there any fatalities? Did the train start from stationary against the signal? Was a conflicting route set ahead of the SPAD? Was the section ahead occupied by another train? Is there a Level Crossing in the route ahead of the SPAD? No Yes, at a platform Yes, NOT at a platform Page 3 of 10
