and light sleepers don't want to stay near the highway or roads
too. end of the day, people will either move away or bear with it.
even now people will hesitate if their house is near the tracks or
a highway as they will be disturbed.
It is a concern, but I seriously doubt if it is a big concern
for the operators/regulators.
that's true too
but I wouldn't want to be the engineer needing to do the
mainteance, and yet get interrupted every so often by a night train
that needs to pass.
I would rather work the full 4 hours and ensure everything is
sui sui before letting the first train in the morning run...
Anything wrong with the track and the train goes haywire... sure
kenna big time...
