    There are certainly some very valid points in your post Chris, I think I and many other members would appreciate your future input into the forum and welcome.

    As to moderation and the removal of posts we try to edit or remove as little as possible. Considering the number of posts per day very little ends up in the bin, sometimes a week or two will go by with nothing new appearing in the bin except the odd duplicate post which can only be a good thing.

    As to 70013, well done to the 5305 Locomotive Association on the completion of repairs and hope all is well with Ollie now.

    Neil.

    This type of occurrence is nothing new, it happens all the time and to illustrate what I mean let me quote from ' Wellington, The Iron Duke' by Richard Holmes pub Harper-Collins p144 regarding the letters written home by officers of all ranks, in the aftermath of misfortune on the battlefield , " Wellington was exasperated by it all; 'as soon as an accident happens, everyman who can write, and has a friend who can read, sits down to write his account of what he does not know". Now this was 1809 in Portugal & Spain, so all this trial by internet forum is nothing new, one must always bear in mind that 99.95% of what is written is pants (including doubtless my contribution) and not really worth attaching too much significance.

    OK back to thread ....... I can only think of 2 cases where piston rings break, poor installation methods (rough) or possibly as result of a massive slip. Now poor installation, rings would have given-up probably within 5 minutes of first movement, not likely here. So question to anyone who was fortunate to be on board, did loco slip up the hill in Anston Stones Woods? Its that dank slimy sodden grim dark wooded valley soon after Brancliffe Jct and renound skating rink for heavy ladden 66's sliding down the gradient with wheels locked while at 30mph. If a momentous slip uphill did occur it can be enough to bend rods (aka Blue Peter) but a heavy slip might just have been enough to do some mischief. Anyone on board please speak.

    .......and if you think I'm talking drivel ...... you're quite right ......... just ignore me & my post !!! And well done all involved in repairs to Ollie, good show!

    I think Ollie was slipping quite a bit as it climbed Shap on February 25th.

    I am more interested in how they managed to replace the rings. Not knowing exact dimensions, was the crosshead split from the piston rod or was there just enough distance to allow the piston head to exit the bore at the front? Either way that's quite a job to undertake in the pouring rain away from a decent base. I groan about doing that in miniature where the parts weigh nothing!

    Amazing work in difficult circumstances. Looks like the railway version of the AA with the recovery van in the background!

    In the the photo's linked above it shows that there was enough room to allow piston head to exit bore without removing crosshead. In link in previous post if you click on "photo" you can see the series of pictures. In the photo linked to the piston head is clear of bore & being worked on, crosshead still attached, con rod small end on ground.

    That's what I hoped but from the picture angle I could not see if the rod was still attached. In the past having had to split one of these it was not an easy job and it took heat, hydraulic help and a bit of gentle 'talking to' with a hammer, and that was only a 2' gauge loco.

    There is a great deal of difference vetween a few mild slips and the violent uncontrolled one that might cause this type of damage.

    Agree, have only seen video but slips were well controlled & I doubt motion got any where near design speed. Brits at one time had a reputation for rings failing and there are umpteen reasons why they would

    Being on the train in question I would have rated them as slight, caused by an over dosing flange lubricator according to the crew. Also consider that 70013 then arrived in Carlisle, returned to Carnforth via Settle and later the following week an engine and coach move to Southall. It would appear the problem only surfaced after the run up the ecml.
    Regards, John.

    From the 'clonk' in the last but one shot of the above video it sounds like a bit more than a broken piston ring to me. Hope I'm wrong, though.
