Before the installation of wayside signals, The NYNH&H used a manual block system, with most of them being a tower and interlocking as well. This system was in use after the Civil War until the early 20th Century. When the NHRR expanded the main line from New Haven to New York from 2 to 4 tracks, most of the block stations remained, and still used this system. The home board could not be cleared for following movement until the train ahead cleared the Home Signal at the next block station. This RR did not use this system like they could have, as it was set up for Eastbound movements on tracks 2 & 4, and Westbound on tracks 1 & 3. They could have used all the tracks like they do now, in either direction, but they did not take advantage of this. Some of the certified Old Timers told me about this when I was in High School in Milford CT. around 1963/64. There was one fellow who had been a Boomer, and who came back to the NH Line to retire, He was about 95 when I met him then, and he was very knowledgeable on this system. Ten years later, when I hired out as an Operator, this old system was still known about and discussed.

When the wire was installed, the RR also installed wayside signals and electric locking in all the interlockings that remained, where there had been Block only Stations, like SS 72, there only remained wayside automatic signals that performed the same function as the manned stations. This took place from 1900 to 1918, beginning in the west end, from NY to Stamford, and eventually they strung the wire all the way to New Haven by 1917-18. It was a monumental project, similar in scope to the elevation and expansion to 4 tracks in the 1890's...All of this was done without the Government paying a dime for it.
written by Dale Martin,ex New Haven operator.

The following are the track diagrams when this operating system was in place. Unless noted they are all NYNH&H. In some instances after the wire was installed they became full blown interlockings. All came via Dale Martin.

I will list the diagrams in sequential order,as much as I can.
