Surprised this hasn't shown up here yet. The new built A1 "Tornado" suffered damage to the inside motion doing a 90 mph run. See

That Steam Loco was flying.

What  a shame.
Those heavy pieces of motion flapping around at 90MPH, argh.
Surely people involved with the build will still be associated with the project. And a repair job will short sweet and effective. Good luck fellas.

Pretty serious - a real blow to mainline high speed steam as a whole.
Be interesting to see how long it takes the Poms to investigate?

Depends what actually went wrong, the Tornado was designed, carefully built and fully certificated for 100mph main line running. The AI locomotive trust stated in its last press release (3 days ago) stated that the cause was still unknown but the failure was NOT speed related. Like ALL new things it (the Tornado) can suffer from random component failure at any time (Note 1), if all systems were condemned for such failures we would still be living in caves eating raw fruit and veges.

Note 1: Its EXTREMELY expensive to build something 100% percent reliable and its usually ONLY reserved for items that simply MUST work first time an example of such hardware is railway signalling equipment (which is why its SO expensive).

Wish the local mobs would keep their fans updated like this when something goes wrong.

I sometimes wonder if this sort of detail would have been provided locally since it might suggest that a a mistake had been made.
Of course, it would be hard to  deny what happened with the video of the bent combination lever lying on the track....

Congratulations to the Tornado people for the published update both so far as timeliness and technical detail are concerned.

As the Tornado was (and still is) in effect "crowd funded" the people forming the orginisation realised from the first they would require extra good communications and that a professional management structure that fully understood this would be required and that is how it was set up, hence the excellent amount of detail, as the money for the repairs is comming from the general public.

The basic premise behind the funding is that people would readily be willing to donate the value of 1 pot of beer a week to build and maintain a NEW mainline locomotive. A simple and cheap method of collecting the funds was required and they had (and still have ) meetings all around Britain to get interest up and of course to get people to join and donate the value of "one pot a week". They were quite surprised on the amount of support they got and the first club, for the frames was filled within a few months.

Hindsight (and an official report) are wonderful things but 'lubrication' was the first word that came to my mind on hearing of the failure.

It would be an interesting hypothetical technical exercise to see if Tornado could have got home on two cylinders (disregarding delays to other traffic, everything and everybody, (plus OH & S of course).

The failure was caused by the front valve of the centre cylinder siezing, this would mean the lubrication failure was to the centre cylinder, the valves themselves not usually having separate lubrication. This would mean any further unnecesary movement would very likely sieze the centre cylinder itself, this would cause a catastrophic failure, this does not bare thinking about.

I assume they had to disable the centre cylinder to move the machine, I suppose they did the same as when they moved 4014.ie by removing the piston from the cylinder and just leaving the connecting rod and the crosshead in situ.

Note to the above post:

In steam engines valve and cylinder lubrication is usually spread by the steam itself, the lubricant being injected into the mainsteam pipe just prior to the valve chest. What this means is one cannot tow these machines far when not in steam as there is no lubrication to the cylinders, hence the 4014 crew removing the the pistons, rods and the drive to the valves.

I IMAGINE that the valve would need to be centred and the radius rod and connecting rod removed at least. QuestionQuestion

Another update on what's been found, together with the work required:

If this was local we would not have heard a word about it, and the offending loco shoved up the back of rotten row, never to be seen again...
