FRA Rail Operations & Train Handling 2

Question 1

When a locomotive engineer encounters a slow order restricting speed to 25 mph, at what point must the train be at or below that speed?

Accepted Answer

At the point where the slow order sign is posted

Answer

Under FRA regulations, the train must be at or below the prescribed slow order speed at the point where the restriction begins, marked by the posted sign.

Question 2

What is the primary purpose of dynamic braking on a locomotive consist?

Accepted Answer

To convert the locomotive's traction motors into generators to slow the train

Answer

Dynamic braking uses the traction motors as generators, converting kinetic energy into electrical energy (dissipated as heat) to retard train speed.

Question 3

Under FRA 49 CFR Part 218, what is required before a crew member goes between cars of a standing train?

Accepted Answer

Blue signal protection must be applied

Answer

FRA blue signal rules require that blue flags or lights be displayed to protect workers between or under cars before anyone may go between standing equipment.

Question 4

A train is traveling at 50 mph on a 1.5% descending grade. Compared to level track, how will the train's stopping distance be affected?

Accepted Answer

Stopping distance will be longer because gravity adds to the train's momentum

Answer

On a descending grade, gravity works against the braking effort, significantly increasing stopping distance compared to level track.

Question 5

What does the term 'stretch the train' mean in rail operations?

Accepted Answer

Allowing the locomotive to pull ahead until all slack is removed from couplers

Answer

Stretching the train means allowing the locomotive to pull forward until all slack in the couplers is removed, creating a taut train condition.
