A pole route (or pole line in the USA) is a telephone link or electrical power line between two or more locations by way of multiple uninsulated wires suspended between wooden utility poles. This method of link is common especially in rural areas where burying the cables would be expensive. Another situation in which pole routes were extensively used were on the railways to link signal boxes. Traditionally, prior to around 1965, pole routes were built with open wires along non-electrical operated railways; this necessitated insulation when the wire passed over the pole, thus preventing the signal from becoming attenuated. At electrical operated railways, pole routes were usually not built as too much jamming from the overhead wire would occur. To do this, cables were separated using spars with insulators spaced along them; in general four insulators were used per spar. Only one such pole route still exists on the UK rail network, in the highlands of Scotland. There was also a long section in place between Wymondham, Norfolk and Brandon in Suffolk, United Kingdom; however, this was de-wired and removed during March 2009.

Famous quotes containing the words pole and/or route:
“This man was very clever and quick to learn anything in his line. Our tent was of a kind new to him; but when he had once seen it pitched, it was surprising how quickly he would find and prepare the pole and forked stakes to pitch it with, cutting and placing them right the first time, though I am sure that the majority of white men would have blundered several times.”
—Henry David Thoreau (1817–1862)
“The route through childhood is shaped by many forces, and it differs for each of us. Our biological inheritance, the temperament with which we are born, the care we receive, our family relationships, the place where we grow up, the schools we attend, the culture in which we participate, and the historical period in which we live—all these affect the paths we take through childhood and condition the remainder of our lives.”
—Robert H. Wozniak (20th century)
