This four cylinder compound tour de force is coal fired, with piston valves and four-channel radio control with manual override.

Alongside a Nord 3500 Class
This side by side comparison shows wildly differing approaches to making powerful compounds for lightly laid tracks. They are both 1911 builds, superheated, following earlier saturated versions of 1908. They are both less than 17 tons maximum axle weight and both are roughly the power of a Black 5. (Both classes have two preserved examples in existence.)
The 310, along with some 1000 other Austrian locos, burnt oil on the same basic system as Holden's oil-over-grotty-coal-bed arrangement on the GER. When WW1 cut off the oil supply (which John guesses was Romanian) they all went over to 100% grotty coal.
John points out the impossibility of building this locomotive in 10mm Scale.
It's been a thirty year project and, if he were to start again, he'd use finer wheel standards.
