LNER 4771 Green Arrow

That's great news Anthony. Like you say, technology and techniques continue to improve and it would be great to see the V2 on the mainline.

No promises mind folks, got Taff Vale 28 to sort out before the V2.

 

What is the story with 28? I know it was at the DFR, now at Llangollen...? What next? Would like to see it running, as something of a South Wales Railways enthusiast.

 

We're actively working to find funds through a very interesting and exciting idea (well, it's exciting to me...)

 

Do keep us updated as you are able and allowed, sounds interesting to me too!

 

Anthony, am I doing more than just reading what you have said? I've already done 10 jumping jacks in case you have a plan for the V2!!!

 

My thinking is along the lines of 4472 will not be the basket case she was when purchased by the NRM, this time she should be looked after and should with a proper maintaince schedule should need nothing like what she has needed, next time round, and in some 6 years time, who knows what the situation will be anyway, will steam still be allowed on the mainline? anyway getting back to 4771, if she is sound mechanically and if as much as possible of the work can be done in house what would the likily cost be ? plus how many visitors would be interested in seeing what an overhaul actually entails? and on watching yorks restoration team at work, either from the public gallery or in an on line blog want to support it financially

 

2500 first if all is well and money is forthcoming...and let's not forget the latter is the most important, and the hardest to get...but let's finish the A3 before we do any more. There are over 20 NRM powered vehicles in operation or under overhaul at the moment, an unprecedented number - so in no way a "Stuffed and Mounted" collection as many would have us believe.

 

Oooooh! You are a tease! One of my biggest regrets was being unable to accept an offer to "play" with No. 4771 on her last day in traffic, other commitments meant I had to head off south in a hurry......

Sorry to have misled you there Foxy, I was referring to Taff Vale 28...

 

Just found this clip PSOV Awsome Power & Performance Green Arrow on Upwey Bank - YouTube
The sound demonstrates why we need a V2 back on the main line. Just awesome.

 

Yes please....one of my favourites.....

 

Awesome music!, and doing all the work too. The Tractor on the rear was only taking its own weight by the sound of it

 

With green arrow it will need the same amount of boiler work as flying Scotsman but couldn't the original mono block be repaired using modern techniques like boring it out and having liners pressed into it making the cyclenders integral again and have the passages beefed up with steel sections and have steel plates and bar screwed into the block to strengthen it?
just and idea and it will cost less then making a new one and will fufil the originality argument
thanks

2 Clips from the fantastic Mike Snow which shows that even in the last few weeks of her ticket and on reduced boiler pressure she was in fine form. Please let her roar again!

 

I think the true evidence for that statement was in her last run. From 28secs onwards...

I think it is a case of cost and historical integrity. The NRM understandably have standards that they stick to when they are conducting an overhaul - once it has been decided one can go ahead.

[wibble]If it were officially sanctioned, you would almost certainly be looking at a new monobloc in my opinion, as you would not want to mess around with the old one excessively from a historical perspective, and even patched up it would be a constant source of worry. So you'd need a new monobloc - possible, but dashed expensive. There was a ballpark figure of £400,000 floating around a while back, I'm not an engineer or an accountant so I don't know how realistic that is. But let's go with it.

Then you'd need the work on the boiler. As shown by the reduced boiler pressure at the end of her ticket, the boiler is tired. So let's look at the same again on the boiler. Remember, it's an NRM overhaul so it'll be to top-spec standards and where possible utilising 'how they'd've done it then' tech, not 'this is what we've got now and it's easier and cheaper' tech. So let's go with another £400k. We're up to £800k.

Finally, the general chassis, tender etc. I believe she was withdrawn just before OTMR became obligatory, so she'll have TPWS but not OTMR (I think). So let's just say for security of figures another £200k for the chassis and ancillaries.

And then let's add another £200k for all the unexpected nasties you'll find along the way. Total: £1.2million. Jeremy! Over here!

[/wibble]

Of course, if the P2 project doesn't come off for the A1 guys...

...and if the monobloc can be repaired, then the whole thing becomes a lot more feasible, in time.

 

It might well be from the same respected engineer but the same comment (i.e. the mono block could be repaired) has been made to me. I was lucky to be on the train when on the two occasions 60800/4771 left Kx in preservation. Very very special. Would be great to think it could happen again one day.

 

well apart from the boiler which is know to be tired which would be a flying scotsman boiler job but it depends on the cracks in the mono block casting they cant be too bad as it made it up the nymr for its last run so it could be in better condition than first thought? and if the cyclenders were bored out another 6 inches in diameter a steel tube with 3 inch thick wall could be pressed in and this then machined with ports so this would provide increased structural strength to the mono block with some more of the block ground out by 3 inch square and steel square bar placed in and welded to the new cyclender liners making the whole structure rigid and relieving the twisting load on the casting, the same could be done with the piston valves if needed then the cracks could be ground out and metal stitched together and to the new metal sections in the block it will be a big job but it will pay off in cost and effect so it would cost about 150,000 to do the cyclenders and the boiler would cost 250.000 to to as that's what scotsmans eventually cost then the chassis need stripping rebushing, remetaling and possible retyering which will cost 150,000 to do then all the mainline gubbins at 200,000 so thats 550,000 to get her working then 750,000 for full mainline big money but achievable i think with support thats been shown and how useful and versatile the loco would be to the nrm so if the nrm took that route in id say 7 years time she could be running again.
thanks

After reading that i am totally speechless .
