Re: SMART full passenger train service to begin August 25, 2017.
SMART is not yet PTC certified; has RSD approval (a fact not disclosed by any other media)
"An FRA spokeswoman said while SMART is not yet PTC-certified, it has “revenue service demonstration (RSD) approval, which means it can test and run trains with PTC and report to FRA all anomalies, at real time, so that we can determine whether they can continue with their PTC system in service.”"
