The normal position of such a switch is in the center and to activate, the person would move the switch to the desired position either “on” or “off” to achieve the desired result and the switch would then return to the center position. A momentary switch is usually used when a device is controlled from more than one location so that one switch does not preclude the device from being operated from another. |

Leaving Hoyt the 25 minutes of running time ensured the points of heat set at terminal were on and the cars ready when they left Grant Avenue. |

Ouch.I suppose I must have remembered the track wrong, otherwise I would expect it to say "on", though. Or was it the reverse - turn off the heat when going northbound? |

You are talking R9 R10 not cars with modern HVAC blowers which heat up even faster with layup heat in the yards. other thing I forgot to mention when I mentioned points of heat the R1-R10 had 3 heater switches 2 for car and one for corner seat off cab heater so at the terminals like Rockaway park of Euclid heat fan PA on number displaying # for points of heat required for each car when you did a put in so in very cold weather all 3 points of heat would be on it did work. |

Now that you have mentioned it, I recall many years ago seeing signs posted on the outside wall of the dispatcher's booth on the southbound platform at Continental Avenue. I remember seeing a sign that was lettered "BMT Heat Fans" with numerals posted. |

Furthermore the momentary sign you saw at J street or Hoyt applied to heating only. If the sign at Rockaway park said fans on heat off the momentarie's were already on when the train left there put in assignments |

I lived in Seattle and it had a lot of trolley bus routes, plus the original tunnel dual mode buses used wire but were problematic. The last time I was there about 10 years ago they had switched to hybrid battery powered buses in the tunnel. Putting the poles up and down required manpower too. These were all suburban routes IIRC. The local routes were on the streets. Now the light rail uses the tunnel too. I must have left before the tunnel was built as I don't remember construction downtown. I've only been back 3 times and the last trip I took the light rail from the airport. I can't recall which of the other times I was down there. |

True, older equipment, but I assumed it was a resistive heater and those tend to turn on quickly. But I suppose railroad-sized heaters have complexities which I am not considering.So, it sounds like the heating system for the passenger compartment was: - 1 point of heat for half strength - 2 points of heat for full strength - Optionally also fans to blow the hot air around? Or did that sign refer to the overhead fans for cooling? |

If I remember from my days as a M/M the R-10s did have an elementary form of thermostatic heating but it still needed to be turned on or off at designated locations, The R-1/9s had actually 4 points of heat operated bt 3 switches on the back panel in the cab. 2 of the switches were 1 point each and the 3 switch was 2 points. The number of points of heat to be put up was posted on a heat/fan board at the terminals and there were 2 boards, one for R-1/9s and the other for R-10/16 cars. |

It used to be that lights were to be turned off at the first station in the open after leaving the subway and turned on at the last station in the open before entering the subway. On lined like the Sea Beach the lights were to be kept on since the trains were going in and out of tunnels for the entire route. IRT and BMT prewar equipment lacked trainline control of both heating and lighting so on that equipment the heat and lights remained on at all times. I seem to recall that the Multis had a semi trainline light control that would turn the lights on and off in all cars in the unit and I remember seeing the C/R going between the units to turn the lights on when entering Essex St. |

The sign for fans was denoting either on or off. if the 600 volt fan switch was left on then the momentaries turned them on so the terminal boards mandated how the car switches were to be switched during putins or conductor train checks. When I worked Rock Park or Concourse Yd I also hooked open the storm doors in Summer except during rain for comfort and for my convenience checking the cabs and door operation during put in walkarounds. On the R27s the illuminated side signs were sometimes problematic, the heat was GREAT but reliable indication was shit. I remember the GE R30s had 1 switch of heat new thermostats during overhaul controlling both fans and heat, toasty cars in Winter and not exceptionally hot in Summer. The heat switch setup should have been the same from R15s and up with only one breaker and fuse for the entire car with the lighting setup based on 600 fuse for each SIDE of car. I cant say my school car gave me a point value on heat as the R10s were going. perhaps they did and I don't remember it |

The only issue with that being this board is located facing the Northbound Crosstown track, not Fulton. Meaning GG conductors observed this board. I've recently passed by the board and it's still there just as pictured.I can only think maybe the sign was moved and reused from another location and the R1/9 text never removed. |
