Posted by randyo on Mon Apr 9 14:09:37 2012, in response to Re: March 31, 1977 - The Last R-1/9 Run In Service, posted by SelkirkTMO on Mon Apr 9 02:34:59 2012. At all terminals, there were heat and fan boards which posted the number of points of heat that were called for based on the weather forecast for the day and issued to the terminals by the trainmaster's office (later the command center). The same was for fans and the number of windows per car that were to be opened. The R-9s had 4 points of heat maximum on 3 switches. One of the heat switches turned on 2 points and the other 2 1 point each. The BMT steels had 3 points although the amount of heat provided was probably the same as the R-9s, just divided up differently. The heat and fans on the R-9s could be energized on the entire train from the cab unlike the BMT steels and IRT prewar cars which had to have the heat and fans turned on or off on each individual car. Once cars with thermostatic controls arrived, the heat and fan boards diminished in significance since they only applied to cars without automatic climate controls of any kind. |
