What is a potential consequence of low battery voltage on a train?

Low battery voltage can lead to a variety of performance issues in a train, and one of the most notable consequences is reduced speed. When battery voltage is low, the electrical systems that power various components of the train may not function as effectively, resulting in a lack of sufficient power to operate the traction motors at their full capacity. This can cause the train to run slower than normal.

It's important to note that while the train may experience a decrease in speed, it typically will not come to an immediate stop unless the voltage is critically low or falls below a certain threshold where the systems fail to operate altogether. However, this is generally not the immediate effect observed with low battery voltage. The flickering of lights can occur due to insufficient power supply but is not typically regarded as a direct consequence impacting train operation the way reduced speed does. As for speeding up, that is contrary to what happens with low voltage; it would not provide sufficient power for increased speed.
