I’m not sure of the accuracy of the speedometers, but the problem is often with the calibration of the GT signals. Regardless of what MPH is displayed, it’s still up to the T//O to keep the train under sufficient control so that the signals will clear. As for the T/Os being expected to bae able to “feel” the speed of the train, while exact accuracy of the speed is not fully possible, any T/O worth his/her sale should be able to tell the difference between 10 MPH and 30 MPH. When I took the M/M test in 1968, all candidates had to be able to estimate the speed of the trains at various locations as specified by the examiners and indicate such by stepping on a pedal attached to a device which would recored the response. We were also required to make 3 stops at designated locations making 1 application and 2 releases the last of which would be made after the final stop with 10 PSI of air left in the brake cylinder as shown on the air gauge. Until the arrival of the R-44s, no NYCTS equipment had speedometers at all. |
