The electrical isolator of the New Carrollton Storage Yard from the rest of WMATA’s track system has greatly reduced the stray current activity in the vicinity of the yard. Isolation of this storage yard has proven so successful in controlling stray currents that WMATA has provided for all future yards to have the capability to be easily isolated. The isolation of rapid transit storage yards will not eliminate all stray currents or be successful under all conditions but it is one proven method that should be considered in the design and operation of rapid rail transit systems.
