Stop & Stay. Call OCC.
Train movement on mainline tracks against the normal direction of traffic without signal protection is known as?
A Wrong Rail Move
A Train Operator is instructed by supervision to bypass the next station. What is the proper procedure for bypassing that station?
Answer that station at the maximum allowable speed, sounding a short series of blasts of the horn at the entering and leaving ends of the station while reducing speed to no more than 15MPH as it is leaving the station.
When backfeeding the R62/R62A what is the minimum Straight Air Pipe pressure?
105
A Train Operator must not leave the terminal in customer service if their train has one of the following that’s inoperable:
A) One Sealed Beam
B) Horn not working
C) No primary indication but alternate indication is working
B) Horn not working
On R62/R62A equipment, just before cutting the train, a Train Operator notices that they have no indication. This is?..
Normal as the shutter doors are open. The TO must utilize the door bypass to move the train.
On New Tech trains, prior to
performing a cut or add, what must be done with Route Programming?
The routes must be canceled.
A TO is moving a train onto a track that has another train, but that train has a red flag on the front of it. How close can the train get?
60 feet
During some yard moves, a train might be stopped in a location such that there is no signal between the front of the train and the switch. This is known as?..
An Incomplete Move
A flagger equipped with a red flag/light, a white light, a portable trip and a whistle must be stationed at a minimum of?..
150 feet from the beginning of the work area.
TO’s encountering a set of caution lights, in which only 1 is lit, should?..
Proceed as if both lamps were lit and report it to the flagger.
The postions of the brake handle are (clockwise)?
- Handle off
- Emergency
- Full Service/Charge
- Snow Brake
- Running Release
- Full Release
A TO, performing a move in the yard they are working in, hears 1 (one) long horn coming from the tower. What is this audible signal requesting?
For all trains in the immediate area to come to an immediate stop.
When moving cars into the inspection barn, what are the required safety stops?
- 3 car lengths
- 50 feet
- 10 feet
- 2 feet from standing cars
After coupling an R142, the TO realizes they made a Soft Add. After uncoupling and setting up to make the add again, the TO must ensure that they add from how many feet away?
2 feet away
A Facing Point Switch is best described as a switch that?..
Has its switch points facing the TO.
What is the MAX speed when moving left or right over a switch unless otherwise posted?
10 mph
The difference between an Interlocking Signal and an Automatic Signal is, an Interlocking Signal…
- Can protect a switch, while an Automatic signal is used, primarily, to indicate track occupancy ahead.
- Has an ‘X’ survey plate on the front or side of the signal.
A fixed signal that may or may not have an associated stop arm which is used for slow speed movement is?..
A Low Home Signal
