This is from Wikipedia, did the cars ever return to use?

"6050-6051 suffered major body damage in a derailment at New Carrollton Yard in January 2013. 6050 was sent to Upstate New York to be repaired at the Alstom Plant. 6051 is currently stored at Greenbelt Yard."

6050 was returned to Greenbelt last year and the pair was mostly put back together, but as of yet not fully completed.
