Maybe they'll learn that they won't actually have to install new catenary because old school engineers actually knew what they were doing. Oh wait, its Federal money so who cares if its actually needed or not.

The NEC is straight as a board from East Junction, Attleboro to the very slight curve at East St., Foxbororough. And that curve can probably get taken at full speed. It doesn't do any kind of curving that would require slowdown until S. Main St., Sharon about a half-mile south of that station. About 15 miles of total straightaway.

Even on a relatively "podunk" line like the one from Zaragoza to San Sebastian, Spain, one sees the characteristic weights and pulleys of CT catenary.

The pulleys and weights are clearly visible along NJ Transit's North Jersey Coast Line on the segment from Matawan to Long Branch, which was electrified in the late 80's. (I think electric service beyond Matawan started in 1988.)R36 Combine Coach wrote:Is constant tension used in the rest of the world (Europe, Eastern Asia/Far East) where speeds are rated at 186 or higher?Yes, and on some slower lines.
