Why do I hear a train when there is none?
At night, the air near the ground can have a different temperature than air only a few hundred feet above1. This affects the transmission of sound waves. There is usually less ambient noise after dark, so the distant train sounds louder. As pointed out elsewhere, maybe the trains don’t use the horn in daytime.
What does a train sound symbolize?
A train whistle or air whistle (originally referred to as a steam trumpet) is an audible signaling device on a steam locomotive, used to warn that the train is approaching, and to communicate with rail workers. Hence a means of warning others of the approach of a train from a distance is necessary.

The reason that trains honk their horns so much at night is because it’s dark and the trains aren’t so easy to see.
