Q

TB 70 METRO LIGHT RAIL LINES

Light Rail Vehicles (LVR) consists of track and stations that are fed electrically by a Catenary System as opposed to a third rail system like the Red/Purple line.

The 34.5 kV AC is converted by a transformer/rectifier to 750-volt DC and fed through the Pantograph via Catenary lines in order to operate passenger vehicles.

Q

TB 70 METRO LIGHT RAIL LINES

The “Light Rail” Vehicle (LRV) is an articulated (flexible in center), six-axle rail vehicle, with an operating cab at each end allowing for bi-directional movement. The ends of a LRV are referred to as the “A” and “B” ends.

The designation “A” end is merely the end of the vehicle, which serves as the point of attachment for the Pantograph.

Q

TB 70 METRO LIGHT RAIL LINES

Each car is 90’ long and approximately 9’ wide. The height, measured from the top of the tracks to the roof of the train, is 11 1/2’. Its maximum height of 23’ 6” is reached when the Pantograph is fully extended.

From the floor of the car to the railroad bed is 39”. The maximum capacity of each car is 237 passengers.

When filled to capacity, 157 passengers will be standing and 76 passengers will be seated.

Q

TB 70 METRO LIGHT RAIL LINES

Activating the door release (by pulling down on the handle) will relieve air pressure from the latching mechanism, allowing the door to be manually opened. A four-to-five second delay will occur before the doors can be opened; this is due to the rate of air pressure escaping the system.

Q

TB 70 METRO LIGHT RAIL LINES

The Pantograph is extended less than ____ pounds of spring pressure and can be lowered electronically from the Operator’s cab or manually via a foot pump. The pump is located under the second forward-facing seat (left side) of the car’s “A” section.

A

21
Q

TB 70 METRO LIGHT RAIL LINES

When manually lowering the Pantograph, listen for the lock to “click.” Failure to engage the lock by fully lowering the Pantograph will allow the spring tension to raise the
Pantograph once again and cause the vehicle to become re-energized. If multiple vehicles are coupled together, the Pantograph on all vehicles must be lowered.

24
Q

TB 70 METRO LIGHT RAIL LINES

“Caution!!!”, after the pantograph has been lowered, do not climb on top of the LRV “A” section in and about the pantograph, as the LRV has capacitors. The bleed down resistors short out the capacitors to deenergize the pantograph area, however, all circuits must be functioning properly for that to occur. It is recommended that you wait ___ to ___ minutes prior to working on the roof area of any pantograph”.

A

5 to 15

25
Q
