LEC Train Handling and Performance

Question 1

What is the primary factor affecting train acceleration?

Accepted Answer

Answer

Engine power and track conditions.

Answer

Engine power and weather conditions.

Answer

Track conditions and train length.

Answer

Weight of the train and brake performance.

Question 2

Why is it important for locomotive engineers to understand train braking distances?

Accepted Answer

Answer

To avoid overspeeding.

Answer

To calculate fuel consumption.

Answer

To ensure safe stopping distances based on speed and track conditions.

Answer

To improve the train’s acceleration.

Question 3

How does the load weight of a train affect its performance?

Accepted Answer

Answer

It increases fuel efficiency.

Answer

It reduces the time needed to accelerate.

Answer

It requires more power to move and increases stopping distances.

Answer

It makes the train more stable.

Question 4

What is the effect of a sharp curve on train handling?

Accepted Answer

Answer

It causes the train to accelerate.

Answer

It increases braking efficiency.

Answer

It increases the risk of derailment, requiring slower speeds.

Answer

It decreases train fuel consumption.

Question 5

How should a locomotive engineer handle a steep downgrade?

Accepted Answer

Answer

Increase throttle to maintain speed.

Answer

Apply brakes to prevent the train from accelerating too much.

Answer

Turn off all braking systems.

Answer

Switch to a backup locomotive.

Question 6

What is the function of dynamic brakes in train performance?

Accepted Answer

Answer

To increase train speed.

Answer

To reduce the need for friction brakes by using traction motors to slow the train.

Answer

To charge the train's batteries.

Answer

To improve engine performance.

Question 7

Why is it important to monitor train speed in real-time?

Accepted Answer

Answer

To monitor fuel efficiency.

Answer

To prevent accidents and maintain regulatory compliance.

Answer

To increase braking distance.

Answer

To track cargo weight.

Question 8

What effect does train length have on its stopping distance?

Accepted Answer

Answer

Shorter trains stop faster.

Answer

Longer trains require a longer stopping distance.

Answer

Longer trains stop more quickly.

Answer

Train length does not affect stopping distance.

Question 9

What should a locomotive engineer do when approaching a signal indicating caution?

Accepted Answer

Answer

Speed up to clear the area quickly.

Answer

Slow down and be prepared to stop or adjust based on the next signal.

Answer

Continue at the same speed.

Answer

Ignore the signal if the track is clear.
