> And don't think that Dr Robinson's invention of the closed loop track circuit fixed it all right away. It just made the automatic block signal possible.
As I noted answering your other post, Thomas P. Hall's development of electrically operated autmatic block signals dates to 1866, using track instruments for train detection. The use of track circuits for train detection didn't really get off the gournd in a big way until the PRR adopted them in 1873.
