I fear you may have missed the point regarding the UNDMs.The first D-Train used the original DC motors, so yes, they do understand the original traction equipment.
Vivarail have converted D78s to two car operation. They just did it as an integral part of the D-Train rebuilding process.
For what it's worth, here's the battery prototype operating as a single car.
And the only part of the traction equipment reused on that video was the motors, towhit I was not referring.
