The elevated lines were semaphore signals and mostly interlockingsignals. I have seen "curve signals" protecting some dangerous things such as a local station on a blind curve. In the 1910s the PSC made the IRT install signals but only on the express tracks. But the extension portion of the 3 Ave el route in the Bronx that was built under the Dual Contracts...didn't that have color-light signal on all tracks? |
