A Maryland Transit Administration official said early Wednesday morning that Baltimore's Metro subway had passed reliability tests on its control and collision prevention system.

Conducted in the aftermath of the fatal June 22 crash of two Washington Metro trains, MTA testing engineer John Forbes said a third night of so-called "integrity tests" was completed about 3:30 a.m. and the examination had found "no anomalies whatsoever" in the speed controls on one of the two tracks from Johns Hopkins Hospital to Owings Mills.

Forbes said the other track was found to have no speed control problems the previous night, while a test of the Metro's collision avoidance system last week also uncovered no malfunctions.
