How irritating that they call it “digital”. It uses an electromagnetic force rather than a steam-on-piston force.
Newer versions of both systems are undoubtedly controlled and monitored with digital equipment.
The word “digital” can be dropped from descriptions now because that’s all there is any more (for good reasons).
Digital? What? It’s an electric-magnetic propulsion system. It might be controlled by digital computers, but EM is not digital.
Between a press that deliberately wants to mislead and distort what is reported and a press ignorant of technology, the hope of actually gaining useful information out of anything they report approaches zero.
