In case you missed this nugget in Sunday’s Examiner, Kytja Weir reports that the Tri-State Oversight Committee responsible for oversight of WMATA would like to see some proof that Metro’s decision to move its older, 1000-series rail cars to the middle of its trains is really making things any safer. The newspaper got hold of a letter sent to Metro on Friday which noted that the committee had previously requested that the agency perform a study to determine whether moving the older rail cars would be prudent way back in November, long before the June 22 crash, but WMATA failed to act on the request. Since no formal study on the effectiveness of moving the rail cars has yet to be performed, the committee is scolding WMATA for going ahead with the plan without enough information.
