Name the three hoses to that are located on each side of the front of the locomotive. Name them from left to right.
main res., actuating, independent
This needle on the air gauges follows equalizing pressure.
brake pipe
what is a block?
A block is simply a specific designated section of track that has an entrance and an exit marked off, each block has a signal at it’s entrance.
where do locomotives receive their power source to generate electricity?
catenary
Where are red coil springs located on a Viewliner and why?
located on the baggage car and half of the baggage/dorm car. It is given more tension to prevent excessive lateral movement with luggage and bags.
Why must you slowly bleed out the air of the brake pipe hose BEFORE uncoupling?
*besides hoses whipping around*
It will sense the brakes are in emergency and will dump the air at a rapid rate of 22 pounds per second.
the main res. hose on my multiple unit hoses supply air to which part of the consist?
locomotive
what does ACSES stand for and what does it do?
Advanced Civil Speed Enforcement System
The primary function is to enforce speeds at locations
this feature on the electric motor allows energy to protect the vehicle against line voltage surges and lightning strikes
surge/lightning arrestor
HEP provides what to my train consist?
heating, cooling, and lights
This feature on a locomotive allows the locomotive Brake Pipe to charge the Main Reservoir on a dead locomotive or cab car that cannot produce compressed air and has no means to connect to Main Reservoir air

Can provide tractive effort via diesel power or 3rd rail electrical power
Describe how the brake cylinders work in accordance to the shoe pads
when BC pressure is increased, the air pushes shoes to apply to the wheels. When BC pressure is decreased, the air releases the shoes from the wheels.
