Considering WMATA started running after the NYCTA already had tunnel washing and vacuum cleaning trains, it’s surprising that WMATA didn’t think to purchase such equipment especially since they shut down at night and use of this equipment would be easier than in NY where tracks have to be shut down by GO to do the work. WMATA and other latter day transit systems were supposed to be state of the art and not subject to the problems that the older systems had.The one thing that gives the advantage to NYCT is the way the track is laid in subway. WMATA uses direct fixation track fastener sitting on cement pads on a concrete track bed. NYCT along with many of the subways built during the first half of the last century fastened their track to tie blocks embedded in a concrete track bed. The former is likely less susceptible to stray currents because of the wood under tie plates. John in the sand box of Maryland's eastern shore. |
