Thanks again Richard:rsullivan wrote: Mr. Ed(nhhe52). I recalled wrong. I read New Haven Railroad 1925 Rule Book and here are the correct meanings. The red blade with white stripe and round end is an interlocking signal. The red blade with white stripe and pointed end is an automatic block signal. The red blade with white stripe and squared end is a train order, manual block, controlled block, or a drawbridge signal. A distant signal is the forked-end yellow with black chevron stripe blade. These are described on pages 88 and 89 of that book. I doubt they changed thoughout the years.

I also found a nice website that explains a lot about semaphore signals and devices at http://www.railroadsignals.us/signals/s ... L_DRAWINGS_. The picture at the top appears to be of two upper quadrant short blade automatic block signals positioned as clear to proceed attached to a catenary bridge for eastbound trains on the Harlem Branch it appear at Oak Point Yard. It has a link to the 1930 US&G Catalog of Mechanical Drawings.
Hope the corrections about the semaphore blades reached you before they were permanently ingrained in your memory.
Still haven't found the Shoreliner issue yet.

I hadn’t had the chance to digest it all.
What was the purpous of these double stacked signals? Is the upper semaphore for the signal at the point of the signal and the lower semaphore for the signal for the block ahead?
