For the past 3 nights ive been woken up serveral times throughout the night by the sound of a train honking/blowing the horn. It lasts for 5 to 10 minutes.. Sounds like the train is passing by. I dont understand why ive never heard this before and why it keeps happening the last few days. It is a huge disruption to my and those who live around me's sleep.
