MBTA's Green Line Rail Errors: Unbelievable Mistakes and Worsening Issues
Miles of the Green Line track in Boston are defective due to being built too close together, causing mandatory speed restrictions. The MBTA leadership knew about the defect during construction but continued the project anyway. Transportation engineer Carl Berkowitz expressed shock at the mistake, stating that train tracks in North America are universally separated by rails that are 4 feet, 8 and a half inches apart. The MBTA has not yet announced a plan for correcting the rails.
