Sorry to get envolved in this but Back in the days of steam the days of steam, water trofs were fitted in the lines, that's how they did it none stop and reached the speeds they did.
@ClassA4Mallard its pretty simple actually, the up 844 has 80 inch drivers, the mallard has 80 inch drivers, the up844 has 8 driving wheels, the mallard has 6, the up844's boiler pressure 300psi, the mallard 250 psi, the up844 has a much larger firebox and has bigger cylinders, the up844 also uses lightweight reciporcating parts, bigger fire, more pressure, lighter driving gear, and more wheels means more power and speed
Troughs not trofs.
