If I can remember from my visit to London, the original “Underground” was actually mostly open cut with short potions of true tunneling. It was called the “Underground” simply because its ROW was below street level and when the tube lines were built at the turn of the 20th Century using electric power exclusively the original underground lines became known as “sub surface” or sometimes melt “surface” lines to distinguish them from the tube lines. I have an annual report from the CTA which describes the Congress St Line as being a “subway” even though like London’s original “underground” most of the line is in an open cut. |
