College Special Train and Special Car

[NW Mailing List]

I’m guessing the last sentence meant the special was operating WB on the EB track and Dunlap, looking out the rear, saw the EB signal display Clear after the train passed. Sound like Dunlap didn’t understand how automatic block signals work since an automatic in Rule 251 territory (double track current of track) does nothing more than show the status of the track beyond it which would have been clear. They’re not dispatcher controlled and there is nothing the dispatcher can do to make them display anything else. 

Larry:  You got it.  Not now, but in 1971 one main track was rigged for Traffic Control and the other main track was Automatic Block Signal only.  Apparently , Dunlap wasn't aware of that. HWB
