First two sentences makes clear what this is about:

Diesel-electric locomotives have been barreling along America’s wide-open spaces for generations, and the century-old combination of consistent, high-efficiency diesel engines spinning up generators to power high-torque electric motors has proven tough to beat. Now, Caterpillar is putting that century-old concept to work in an even bigger dozer – and the promised efficiency gains are incredible.

It's not exactly train tech, it's just a diesel generator providing electricity. Not really interesting, reads like an ad.

Also, seriously? New diesel products? In 2026?!

Diesel electric generators are pretty efficient for very off grid use cases. Until we find a energy source as good and dense and light as boom boom liquids we’ll likely keep using them.

The amount of energy they consume, unless you were going to follow it around with a glorified high voltage extension lead there is no other way. In a 12 hour shift they'll use over 1000L of diesel.
