Weird question, why all the sudden is there a bunch of super loud train horns? It feels like it's almost every day at this point when the past 2 months have been quiet.

Union Pacific 4014 "Big Boy" arrived here at the Station Tuesday evening and left this morning. It's the world's largest operating steam locomotive. If you've been hearing more train horns than usual in the last few days its likely from 4014. I

Sometimes depending on the weather & wind direction they will seem louder than normal

Currently at Union Station there is a classic train on display named "Big Boy" that could be the reason why.
