I hear trains going by my rural OK town almost nightly. Those horns can wake the dead, which probably accounts for my crappy morning moods. :-)
Not sure what they’re carrying or where they’re going, but the activity level in this locale hasn’t really changed. If anything, it’s picked up somewhat.
If you live in Oklahoma and the trains you’re hearing are north/south bound then what you’re hearing is Warren Buffet’s tank cars hauling Kanadien oil.
