GEN. REQ. Flashcards
When will regular visual inspections potentially be reduced or suspended?
The line is out of use for extended period.
What will happen inspection wise to an out of use line that is not permanently fenced off from the operational route?
(3pt)
- Section Manager inspections are continued at a reduced frequency
- *Frequency will be decided by TME and RAM, focusing on line-side security.
- Line will be inspected before re-opening. This may be done by low speed cab riding.
What will happen if track cannot be visually inspected (snow, flooding etc.).
(6pts)
TME and RAM will implement alternative measures to confirm lines can operate safely. Alt. measures include:
1. Apply for TNC
2. Cab ride 1 at 2x BVI frequency
3. Clear snow from locations of high risk fastenings
4. Apply ESR
5. Slow speed cab ride
6. Consider need for additional mitigation
What does the track category matrix show?
Category a line falls under in relation to speed of traffic and equivalent annual tonnage that occur.
Which CAT has highest speed of traffic and highest equivalent annual tonnage?
“ “ lowest “
“?
CAT 1A
CAT 6
What does RAM do in relation to track category matrix?
Specifies ruling track for each line on each section of route, taking account of changes in speed and tonnage.
Who anually reviews frequency of inspection plans?
TME
Which variables will change inspection frequency in the review of them?
Asset condition and traffic changes
BVI will include, at level crossings, checks for:
(7pts)
- Deterioration + defects in track covered by crossing surface
- Deterioration of level crossing surface
- Deterioration to trespass guards
- Track condition that may affect safe use of crossing w/ vehicles
- Loose deck units which may tilt under road traffic
- Gaps and steps between deck panels that may be hazardous to pedestrians
- Functioning telephones at unmanned crossings
What is paid particular attention to when inspecting sub- surface components? (4pts)
- Loose, missing or defective fastenings
- insuators and pads
- defective and/or void sleepers
- ballast condition
What should be looked outfor when BVI is at a longitudinal timbered bridge?
(4pts)
- Wheel/rail contact marks (evidence of rail rotation creating wide gauge)
- Tightness of holding down straps
- Voiding at “flying ends”
- Fastening in place and tight
When water has subsided after flooding, check in foot inspection for…
(5pts)
- Debris on track
- Debris in flangeways, switch opening and equipment
- Undermining due to ballast washout
- Contamination of ballast or formation
- Blocked drains
What is to be included measurement wise in Section manager inspection?
(4pts)
- Gauge
- Twist (intervals not > 3m)
- Cross level
- Alignment
What should be checked after water has subsided from a flood?
5
- Debris on track
- Build up of debris in flangeways, switch openings, equipment etc.
- Undermining due to ballast washout
- Contamination of ballast or formation
- Blocked drains
What will happen before a short term traffic increase?
2
- SM inspection, outlining repair work required
- Increase BVI and SM inspection freq. (relevant to amount of traffic and how long it is for)
