Thanks for posting this.N.B. the article states that 90 sec headways or 40 tph operation was possible. They actually operated 36 tph or 100 sec headways, all before CBTC. |

The only thing that M/M were required to know were the actions required to insure that actual operation of the trains, such as keying by, activating the manual stop release etc. Even the Tw/M did not have to learn all the techno babble contained in the article. most of that info was for signal staff and actual signal engineers. |

Although the photo is B/W you will note that the signal plates on the home ball are 2 different colors. On the original IRT signals, the automatic signals had black numbers on a while plate and interlocking signals had white numbers on a red plate. Old IRT interlocking signals only had the lever number but not the chaining number. IND and postwar signals carried both the chaining number and the lever (or button) number. The signals on the Flushing line had the chaining number black on white and the lever number white on red. Subsequent IRT signal installations had both numbers black on white and eventually the signals on the Flushing Line were changed to match. |
