@wheelsdown1 "..it could be slight slippage from one set when pulling away? ie a tiny bit of wheel spin from one set of wheels?"
Yes, that's what meant tho' I couldn't express it good enough. I'll keep in mind the fatwa thing when I approach a railroad crossing the next time - never know whether a furious engineer a.k.a. steam ayatollah stalking me there.. I drive a modular combination which is ca. 25m meter long and that's why a pretty good target for these loco missiles.

true americana there.

@OttovonEarth thanks for your thoughts lets hope you don't start end up with the equivalent of a fattwa against you from the loco-heads. Thinking about it, it could be slight slippage from one set when pulling away? ie a tiny bit of wheel spin from one set of wheels? Its a monster loco though, very impressive.

@wheelsdown1 So they seem - actually, I don't know nothing about locomotives, but maybe those position differences between rods arose when the machine started to move. I suppose the steam presure can be steered independently for its two triple or rather their cylinders (2 circuit?) and another one got more steam and span/slipped..
"Wont be a life altering answer" - Heh heh, waite and see when steam-headed loco freaks see my "answer.."

@OttovonEarth This is a Challenger Series loco... The UP Big Boy is the largest loco in the world it is a 4-8-8-4 truck set up... Search it out... There is still one in Scranton PA...

What a magnificent machine..

I know this is a bit geeky, but the front and rear connecting rods are moving almost simultaneously at times, then later they're almost exactly opposite each other in travel. Could that be through different steel tyre wear altering the wheel size slightly? Wont be a life altering answer, I'm just curious.

Oh what a beautiful sight, Someday I hope I can see a Challenger up close and running. Great Video Thanks

What a great piece of filming of a beautiful subject. Now have a look at the world's newest steam loco. Built in UK from scratch and completed in 2008 after 18 years of planning, "Tornado" is seen on her first mainline speed tests. Just search on 60163 Tornado.

@DrDruidKJunior probably the business special
There is just something that looks so good about steel moving that fast. Please, don't ever let Steam Locomotives fade into history.
