Sounds of the night...loose coupled goods trains, chuffing whistling and clattering, as they take up the slack in a long string of waggons.
Ships sirens, on Manchester ship canal, tugs tooting their replies.
The hum of heavy industry, clattering and banging through the night, long gone now.
Works hooters at start and finish of shift.
Street lighting switching off at approx one am
Milk man delivering milk at five am
