When and Where were these units rebuild? I saw a picture of one in Elmira Heights. I know that there is a CAF USA facility there and an Adtranz proceeded it.
The original rebuilt was to be done at Republic locomotive works in North Carolina.
but after banckrupcy of Republic the first two were moved to Elmira at ABB.
All 10 units were ultimately rebuilt at ABB in Elmira (later Adtrans)
