31st January 2009. Passing near Finchale Training Centre, North of Durham we see 60163 Tornado on its first daylight run up the ECML and its first fully painted in green. Filmed on a Fuji 9600 digital camera set for video
@woodscritter The hand-prepared ROWs you talk about were few and far between and were usually quite short (around 30 miles maximum). The only one to survive complete that I know of is where The Rainhill Trials took place with Rocket. The routes that Tornado regularly uses includes steep gradients over many miles including the Stoke banks on the ECML, the Devon banks on the Great West main line, Ais Gill, Shap & Beattock that include many miles at 1:75. All this with over 300 tons behind
@woodscritter We only ever had one Hudson type (4-6-4) in the UK which was a rebuild from the Gresley "Hush-Hush" experiment that used a Yarrow marine type water-tube boiler of around 700psi. It was rebuilt into a steamliner like Mallard with conventional boiler and numbered 60700, so I could not compare a Hudson with a Pacific.
@woodscritter Sorry, not quite correct. The lines that Tornado runs on frequently have gadients as steep as 1:75. The ECML between London and Edinburgh which is where Tornado's predecessors ran had many miles at 1:200 and the standing start out of Durham over 4 sets of points and on a sharp curve was approx 1:120. I do not know of anywhere in the UK with marked gradients as flat as 1:2000.
@ACLTony Remember that many rail lines in Britain are first on the planet; engines then were very low-power and delicate. Thus the hand-prepared ROWs are close to absolutely flat. Typically around 1:2000.
So, you don't need lots of power or tractive effort on such routes. Tornado is rated about 2000 hp. UK really doesn't have grade crossings, so less impact-protection means lighter coaches.
And ... Tornado is a Pacific-type, 4-6-2; a Hudson-type (4-6-4) would imply higher power potential.

Impressive seeing a Hudson pulling a 13 car passenger train at speed. Nice!
