What should you do immediately after receiving a report that an Underline Bridge has been struck by a road vehicle?
Stop all trains passing over the affected bridge (unless otherwise shown in the SBSI).
Tell Ops Control.
Arrange for a BSE (Bridge Strike Engineer) or BSN (Bridge Strike Nominee) to examine the bridge.
If you are given permission by a BSE or BSN to allow trains to proceed at a specific reduced speed after an Underline or Overline Bridge Strike, what must you do?
Stop each train over the affected line
Tell the driver what happened and the location of the strike
Tell the driver not to exceed the specified reduced speed over/under the bridge.
What should you do immediately after receiving a report that an Overline Bridge has been struck by a road vehicle?
Tell Ops Control.
Arrange for a BSE (Bridge Strike Engineer) or BSN (Bridge Strike Nominee) to examine the bridge.
Carry out ‘Examination of the Line’ regulations - you must also tell the examining driver to stop short of the affected bridge and unless there is obvious damage, debris or distortion - to proceed no faster than 5MPH under that bridge.
If a driver reports back to you that the line appears safe for trains to pass after examining the line following reports of an Overline Bridge Strike, what speed must all subsequent drivers be told to pass over the bridge?
No greater than 20MPH - until a BSE/BSN attends and gives further instructions (stop all trains, reduce speed, etc).
What are the Underline Bridge colour classifications and their associated speeds?
RED= NO trains past until BSN/BSE examines the strike and authorises it.
AMBER= 1st train @no greater than 5MPH, subsequent trains up to 20MPH
DOUBLE AMBER= 1st train @no greater than 5MPH, subsequent trains up to line speed.
GREEN= Advise Ops Control, normal working.
*Always arrange for a BSN/BSE to attend).
Where are details of bridge strike classifications found?
In the Bridge Strike index (in SBSI’s, often also displayed separately).
