The "Red Devil":
There is annoying music at periods throughout the video.
A blog by a "sucker" and a "loser" who served her country in the Navy.
If you're one of the Covidiots who believe that COVID-19 is "just the flu",
that the 2020 election was stolen, or
especially if you supported the 1/6/21 insurrection,
leave now.
Slava Ukraini!

Interesting stuff here:

"Compared to an unmodified Class 25NC, the Red Devil achieved a 28% measured saving on coal and a 30% measured saving on water, measured during freight service, and a 43% increase in drawbar power based on the maximum recorded drawbar power. Its approximate maximum range in full-load freight service on 1% to 1¼% grades is 700 kilometres (430 miles) based on its coal capacity, and 230 kilometres (140 miles) based on its water capacity.[5]"
...but:
"The Red Devil's great power, however, also turned out to be its one weakness. The Class 25NC had already proven to be on the slippery side and the much more powerful Class 26, with essentially still the same dimensions as the Class 25NC, was even worse. It was a poor performer at starting or at low speeds on steep gradients. On its first working run from Pretoria to Witbank in Transvaal, a signal stop on a 1 in 50 (2%) gradient resulted in great struggles to restart, eventually causing about twenty minutes delay. Neither the Herdner valves nor the air sanding seemed able to overcome these problems."
