Q

Will the SCV obey all traffic signals?

A

Yes, however there will be certain intersections where optical sensors will allow the streetcar to proceed through the intersection while all other traffic is at a 4-way stop. These intersections are equipped with a special “lunar bar” type transit signal to assist streetcar operator in moving through the intersection

26
Does the streetcar have a gong bell and horn?
Yes
27
Explain track switch:
1. Tracks that move when manually thrown by a streetcar staff member changing the route 2. Manually operated and contain switch heaters (750V)
28
The transfer power sub-stations will supply specific sections of the track. It may be necessary to shut down how many stations to de-energize the line in certain locations?
2
29
The sub-stations will be protected by a fencing system. The key to the Knox Box is located where?
Near the gate
30
Where are the Emergency Trip Switches (ETS) located?
Outside the door to the Traction Power Sub-Station (TPSS) in a silver box on the exterior of the building. The box is opened using a Knox Box key.
31
Will pushing the Emergency Trip Switch (ETS) kill the power to the streetcar?
It may or may not as the system is built with electrical redundancy. (Other TPSS may feed the system. In addition, other streetcar vehicles moving along the system can generate electricity back into the system through their breaking system)
32
Where are the TPSS located?
1. TPSS #1- Riverfront Transit Center 2. TPSS #2- 101 E Court 3. TPSS #3- 1829 Race 4. TPSS (Yard)- 117 Henry 5. TPSS (MOF)- located inside the south end of the MOF building
33
How many volts is the TPSS?
AC 13,500V in, and 550-1000V DC out
34
What are the specifics of the Overhead Contact System (OCS)?
1. The wire is a solid grooved copper 350kcmil (.592 inch diameter) non insulated wire carrying 750v DC 2. 0-4000 AMPS (taser is .00021 amps, 50k v) 3. Wire is tensioned at 2000 lbs however the tension fluctuates with ambient temperature as the wire expands and contracts
35
How many lbs is the Overhead wire tensioned at?
2000 lbs
36
Do volts or amps kill?
AMPS
37
What is the normal height of the light rail overhead contact system wire?
19' 6"; may be as low as 14' 6" in locations where the OCS travels under overhead walkways
38
What does the pantograph do?
Connects the SCV to the overhead contact system (OCS) to power the streetcar
39
What are the two ways the pantograph can be lowered to de-energize the vehicle?
1. Automatic-push the red button on the right hand side of the drivers console 2. Manual lowering-manually lowered from the B car
40
How is the pantograph to be lowered using the manual option:
In the B car, a shaft is located in the ceiling behind a cover plate. Remove the cover plate with a square key. Retrieve the pantograph manual crank from the overhead compartment. The square key will unlock the compartment. Insert the crank onto the shaft in the ceiling and rotate in the direction noted
41
What is to be done if an incident, such as an MVC, has occurred in a streetcar intersection and streetcar traffic could compromise the safety off FFs operating?
Company officer is to contact Fire Dispatch and request they contact the Operations Center (OC) to temporarily stop the streetcar traffic in the vicinity of the accident
42
Activities within _____feet of the centerline of the tracks could be impacted by streetcar traffic
5 feet
43
If there is an immediate life safety risk, who should be requested?
SORTA/Transdev Streetcar Supervisor through dispatch and push the emergency trip switch at the closest TPSS (which may or may not kill the power)
44
What is the only way to ensure the electricity to the streetcar has been sectionalized and de-energized?
Metro/Transdev personnel will respond and place grounding straps from the OCS to the rail on each side of the incident creating a safe work zone
45
What are the streetcar priorities?
Life Safety Incident Stabilization Property Conservation
46
What does the streetcar operator do if a passenger has a medical emergency?
Will coordinate the next stop location with the OC and Dispatch. The streetcar will ALWAYS proceed to the next stop
47
Once FFs have entered the streetcar for a passenger emergency, what is to be done
Have operator show you the key is out. This engages the brake and disables the throttle ensuring the streetcar won't move. The key is on the left side of the console
48
For a passenger emergency, does the streetcar need to have the power shutdown?
As long as the SCV is operating normally and on the track, the power does NOT need to be shutdown. This way the heat/air and lighting continue to function
49
If the streetcar operator is having a medical emergency they will coordinate with Dispatch and the OC the next stop location for fire response. What happens if the operator becomes physically incapacitated?
The Dead Man switch will operate and stop the vehicle
50
Where is the operator and how can you get to him?
Located behind a glass partition isolating the operator from passengers. A Knox box will be located on the partition with a key to access the operator Make sure to remove to key on the console to engage brake and disable throttle if operator is unable to do so
51
Most accidents with a streetcar vs. car do not derail. If they do derail the operator can usually lower the pantograph and eliminate electrocution hazard. What is the hazard if the pantograph becomes entangled in the overhead wire and the pantograph cannot be lowered?
The entire SCV becomes energized and poses a significant electrocution risk to both responders and passengers who make ground contact.
52
If the pantograph is entangled in the OCS, should an attempt be made to lower the pantograph?
No, the OCS could become damaged
53
What is included the the size up for an accident involving the SCV?
1. Is pantograph raised and connected? 2. Is pantograph tangles in OCS? 3. Is SCV on the tracks? 4. Is OCS intact? (poles or wires down)
54
What is to be done if the SCV is derailed and the pantograph is still in contact with the OCS or lines are down?
1. Do not approach the SCV or track 2. De-energize the OCS 3. Wait to approach the SCV and advise passengers to stay inside until the power is confirmed shutdown by a Metro Supervisor 4. The Metro Supervisor will confirm the appropriate breakers have been racked out and kicked out in the TPSS. The Supervisor should also attach a meter to the line to confirm power is off and attach a grounding strap
55
What is the easiest access into the streetcar?
Manually open the doors by using the exterior emergency door releases.
56
How many emergency exterior door releases are there?
There are 2 releases located on each side, one at each end behind a body panel
57
Does cutting through the body of the SCV provide adequate access to the patient compartment?
No, attack the doors if at all possible
58
The SCV has a bumper and bar ____ inches off the track to reduce the possibility of people or cars becoming trapped underneath?
3 inches
59
SCV's are extremely heavy and unstable when lifted. Lift the SCV as a last result. Metro has a specially designed vehicle to safely lift and rerail the SCV, however the response time is ________ to ________ minutes?
30-60 minutes
60
When is the only time the FD is to lift the SCV?
Only for the rescue of a viable PT
61
If the SCV is to be lifted by the FD, what are the lifting procedures?
1. Ensure key is removed and pantograph is lowered 2. Lifting plates are mounted along the bottom frame 3. If possible, lift the A or B section or both. Avoid lifting the Center section by itself. 4. Utilize a bottle jack and wood cribbing to lift the SCV.
62
Who responds for SCV vs. another vehicle?
1 Engine, 1 Ladder, 1 HR, 1 DC, 1 Medic, SO2
63
SCV vs pedestrian, what is protocol?
1. If victim is out of path of SCV, treat PT like car vs pedestrian 2. If PT is in pathway or near rails-remove key and have pantograph lowered 3. If victim is under streetcar, refer to lifting procedures
64
Is the SCV equipped with a fire protection system?
No, most equipment is located on top. The SCV is specified to NFPA 130, the floor and ceiling have a 30 minute burn through rating
65
For a fire in the SCV, what should be done prior to firefighting?
Lower the pantograph
66
Where is the battery isolation switch?
Behind an access panel in the B section, panel is removed using the square key
67
How is a fire in a TPSS to be handled?
The same as a fire in an electrical sun-station or vault. Don NOT enter or put water on fire until it has been verified it has been de-energized
68
For structure fires along the streetcar path, just standing on top of the apparatus places the FF dangerously close to the OCS. How many feet clearance should all members and equipment be from OCS?
10 feet
69
Does the SCV represent a source of ignition for a natural gas leak in the vicinity?
Yes, notify Dispatch to have SCV operations suspended
70
Who investigates suspicious packages on the SCV?
