trunk line

“So the consumption of water was faster than we can provide water in a trunk line.”

Quiñones said four times the usual demand for water on the trunk line over a 15-hour period led to drops in water pressure.

Stationmasters along that part of Greece’s main trunk line communicate with each other and with train drivers via two-way radios, and the switches are operated manually.

“Opening up the trunk lines and putting all that in, it’s not what people care about or want to see.”

Department of Water and Power has also installed more earthquake-resistant mainline and trunk line pipes in recent years, intended to keep hospitals and other critical sites operating after a quake.
