I live right next to a railway line. There are many freight and passenger trains go by at 20 minute intervals. Passenger trains only during the day, but freight trains throughout the night. I was fully aware, when we bought the house, that there would be trains going by day and night.
But I really love hearing the trains going by. They never wake me up if I'm asleep.
But if I'm having a wakeful night they are very lulling. The tickety boo is more
likely to make me sleep than wake me up. I just think of the driver who is taking freight from the east to the west coast or something. He's awake. So am I.
When I hear a freight train going by at 3am I feel like somebody else is also awake. I don't sleep well generally but I sometimes wish I was sitting next to the driver and going somewhere..
