Well as long as you are such a knowlegable train expert, let me correct a few things that you got wrong in your single mis-informed statement.1) It's J/BDC as in J switch/Build Down Contactor 2) It's not contacts it is a contactor 3) The J/BDC was unreliable moxtly because of two other devices that controlled it (The JMR and the FFR) 4) When the J/BDC failed, it did not close - it remained open - IT DID NOT SHORT 5) When the J/BDC failed, it did not trip a breaker and cause dead cars. 6) When the J/BDC failed, it did not close, allowing coast current to exceed design limits and resulted in overheated grids. So, let's see. You made one statement that had 6 glaring errors in it and still haven't idenified the the primary causes of the R-68s poor performance. Keep trying though. |
