Posted by randyo on Tue Apr 23 12:25:59 2019, in response to Speed, posted by Baltimorerail on Mon Apr 22 13:40:13 2019. As part of the qualifying practical portion of the M/M test, candidates were required to make 3 starts and 3 stops and to step on a pedal attached to a machine to indicate the speed when asked by an examiner. The machine looked like an oversized lie detector and considering the methods used for the M/M candidates to indicate the speed, it was. Candidates were also required to make the 3 stops by applying the necessary brake and make 2 releases leaving 10 PSI in the brake cylinder with the second release being after the complete stop. In reality the test was mostly BS since when I took the test on the Jerome line, there were landmarks along the structure where we were supposed to indicate the speed asked for. During the first run, the examiner would tell us to indicate when were going 15 MPH, on the second run 25 MPH and on the 3rd run 35 MPH. Each one of those speeds had a distinct landmark so it was virtually impossible to miss although a few people did. While the braking part of the practical with SMEEs was relatively easy, in the old days the test was given on AMUE equipment, LO-Va on the IRT, R-1/9s on the IND and steels on the BMT and there was no air gauge to indicate the amount of air in the brake cylinder after each stop. The way it was actually done, was that as long as some air was left in the brake cylinde rafter the stop it would be concluded that it was the correct amount. |
