Dear sirs. In the old times there was in Brazil a system of controlling the the traffic of trains between two stations called "electric staff". By the system a train only could leave the station "A" after receiving the "staff" (a bar of metal that was taken from a device) after the next station "B" had unlocked it by an electric current. Was there a similar device in your country? If so, could you tell me where can I get a photo of the device and details about how it worked? Please, send the answer to jatveiga@terra.com.br Thanks Julio Augusto Toledo Veiga Piracicaba (SP) - Brazil jatveiga@terra.com.br |

The line was abandoned about 1918 or so. Follow the link and scroll down. It refers to the staff system for controlling movement through the tunnel. http://www.netreach.net/~rphillips/_pg3_16.html Don C. old_fxrs@msn.com |

Southern Pacific used the electric staff system on Donner Pass from circa 1911? until double-tracking was completed in the 1920s. Engines were equipped with an automatic staff-exchange "catcher" on the side of the cab, below the window. It was similiar to a miniature mailbag catcher. This is clearly visible in pre-1930 photos of cab-forwards, etc. (this eliminmated the need to stop at each staff-exchange station.) Once "the hill" was double-tracked, the staff system was replaced by automatic block signals. More info is available in Signor's excellent book "Donner Pass". I believe that Northern Pacific Railroad had a similiar system for the single-track Stampede Pass tunnel during the same time period. One oldtimer referred to the staff as "the pickle". doug.w.debs@fcimg.com |

I seem to recall that the Pacific Electric used a staff system on a portion of the San Bernardino line. It was a portion of the line that utilized trackage rights on a SP branch line between near San Dimas and north Pomona. Brian Norden bnorden49@earthlink.net |
