Posted by Q65A on Wed Jan 22 09:19:25 2025 From jonroma.net, an excellent resource for railway signaling,When you open the link, scroll down to the entry for New York City Board of Transportation. There you will find signal diagrams (dated from the late 1940s) for several IRT lines: Old IRT Signal Diagrams |

Great stuff, thanks.One question - the 1947 Map of the Lexington/4th Avenue IRT line appears to show that the southbound local track from Brooklyn Bridge did not physically connect with the southbound track at Fulton Street (there is a gap in the diagram). We know that there was once was a connection, since the 6 train used to run to South Ferry, but that the connection wasn't physically severed until the 1960's and perhaps later than that. So why does the map show that the tracks were not connected? Is it just a reproduction error? |
