Oh yeah, i didnt notice that originally, along with the fact it stops at quite alot of places and stops over an hour in some places, still find it insane though that its a 24 hour path
Lots of possible reasons for 40mph. Is it going tender first? Is it going without parts of it’s valve gear/con rods? Is something on it optimised for lower speed running on the West Highland? Other?

Tender first is normally 45mph, But if the engines running without rods, then the speed will be much lower, most likely 30 mph, with stops to check for lubrication, hot boxes etc,

Piston rods ,are con rods, they connect the motion from the pistons to the driving wheels, the rods connecting the driving wheels are coupling rods,
Was 44781 being towed dead, that would explain why several longer stops were scheduled, for pots to be examined and lubricators to be wound
But why tow her to Fort William, and not back to Carnforth where better facilities if a rod needs re-metalling are?

Yes, that is the reason, its to do with visability whilst running tender first, anyone who has been on the footplate running tender first will tell you how poor it can be some tenders are better than others, for example something with a low or inset bunker is better than say an A4,
Sorry to be thick, but this is being towed by a class 37 + POB - the visibility from the tender will be close to zero.
presumably the speed limitation is due to lubrication and hot box risk etc?

I would have thought so, because normally the engine even if piloted by a diesel, would be in light steam, with the regulator cracked so steam cushions the valves,
In this instance though, the 5 was being towed dead, with con rods removed, the only time rods are removed is if the engine has run a bearing either small end, or big end, or has cylinder issues, such as water carry over that's taken out the front cover, and Fort William I would think won't have the facilities to re-metal bearings,

I thought that the max speed for tender first was more the case tbe tenders, particularly if lower in water and fuel can ride very badly? Or at least I remember am this being mentioned in the Railway Magazine many years ago in a Practice and Performance on tender first running (I think it was a particular region or area but but it was over a decade ago, too long to remember exactly)

Tenders do tend to hunt, that is rock from side to side when leading, I can remember a certain S160, that used to do it up and down at the same time, it tender first even at just 25 mph, was very lively, until you got used to it, you risked putting more coal on the floor than in the firebox.

Saturday’s Cumbrian Mountain Express will be hauled by 86259 to Carlisle then hauled by a diesel across the Settle and Carlisle line before changing back to 86259 at Preston

Does anyone know if Wednesday’s Scarborough Spa Express will be steam hauled as it is pathed at 60 mph max?
Thank you
