A record of events, activities and our work with the Q6



Q6 failure

I have just had a phone call from Piglet who is at New Bridge. The Q6 was being prepared this morning when the blowdown valve stuck open, due to a fracture of the shaft. This may have been caused by a foreign body in the valve.

Mark O'Brien is present and reports no visible damage to the fusible plugs. The plan is to move the engine back to Grosmont and make and fit a new stainless steel shaft.

A photo charter using the Q6 is still planned for Monday.

Uodate 8/11/2018:
A blanking plate has been fitted to the boiler and a steam test is due tomorrow, prior to filming starting Monday. One of the springs had lodged in the valve opening, causing the shaft to fracture. A new Stainless shaft has been made and a new spring is on order. The spare valve in stock is too large.

 

Wednesday 24th October 2018

A fine mild day at Grosmont yesterday with Ian Pearson, Jon Bradley, Nigel Bill and (eventually) myself. After the usual washing up of lots of cups tea was served all round. There was quite a lot going on at the MPD with the steam crane in action lifting S15 No. 825's boiler from a well wagon into the area outside No3 road ready for its out of frames steam test next week. It certainly was of great interest to the visitors, as well as those walking the Rail Trail.

The Q6 was in the Running Shed on No 5 road waiting for a few minor repairs in preparation for its involvement with the NELPG diner on Saturday. The work was being organised by Barney, and two shed fitters, Dougie and Duncan, were given the job of dismantling and repacking both piston glands, while we were given the job of checking out the R/H cylinder non return valve which was leaking oil and steam. We set about by taking out some of the cylinder cladding bolts and removing the oil soaked insulation, finding out later that it wasn't necessary. This was because, when the non return valve was unscrewed from the bottom part (which is screwed into the top of the cylinder where it delivers oil), as Jon started to unscrew the top of the valve it sheared off. Looking at the piece that had come off it was evident that this had been broken for a long time, causing the highly visible steam leakage for many weeks, and it was not the result of any rough handling on our part! After consulting Barney we were told to see Barry Nesom, a volunteer machinist, to make a new bottom fitting with the broken one as a pattern. He did that within the hour. Our thanks to him and the other MPD staff involved for their help during the day.

Q6 RH cylinder non return valave with new body fitted into cylinder - Ian Pearson

Lunch was had alfresco on the picnic benches outside Deviation Shed, possibly for the last time this year in view of the forecast for wintry weather this weekend. After lunch the non return valve was refitted, with the new bottom end into the cylinder (see photo). It was then primed with the bleed screw opened to check oil was flowing through. This was satisfactory, and the bleed screw tightened back down. The insulation was repacked and the cladding bolted back up. Other jobs completed were the tightening of the L/H trailing brass oil box feed pipe, and fitting of a thicker shim on the trailing L/H coupling rod bush. We then spent the rest of the day cleaning the running plate, oiling the axle boxes, and cleaning the inside motion. While Nigel Bill was cleaning round the lubricator, he found an outstanding defect - a loose lubricator fixing stud which he removed. It had a defective thread, so he obtained a new stud and fitted it. Our work was all signed off by the MPD.

Elsewhere, the J27 was working on the, now 4 coach, teak set diagram. With the removal of the S15 boiler for 825, the tender and frames for Hartland have gone onto No 8 road in its place. Once a successful boiler inspector steam test has been carried out on the boiler (provisionally planned for the end of next week), the S15 frames and tender will move out of No 7 road for the boiler to be dropped in. Lucie has also moved out of Deviation Shed, and is now in the Fitting Shop waiting to be rewheeled and the boiler to be completed. Putting it back together should then be a relatively quick job, but will it be ready for Santa steam heating duties at Pickering in time.......?

Nigel and I also had a walk up the headshunt to see what we thought was the Group's V2 tender underframe, which is a possible candidate to replace the existing K1 tender in due course. We also moved a bench from the side of the Running Shed up to the viewing area outside Deviation Shed. After restoration, this is planned to be a memorial bench for the late Alan Toomer.

 

Wdnesday 17th October 2018

Ian and I were at Grosmont today.

The Q6 was out of traffic with another broken bracket on the fall plate, which occurred on Saturday. That had since been repaired and was refitted by the MPD during the day, along with the regulator gland being repacked. The piston packing has also been repacked and a water change will be carried out before it returns to service on the diners over the weekend. It was also being cleaned. In the meantime, the J27 was in service on the teaks, and sounded fine as it went past Deviation Shed on the 12.30 from Grosmont.

At Deviation Shed, Ian washed up all the dirty tea mugs, while I did the monthly check on the defibrillator and then trained Ian on the checking protocol. There were also a number of visitors who were happy to chat. With little more that could be done, we both left in mid-afternoon.

Elsewhere, the boiler for 825 is due to have its out of frames steam test on Wednesday next week and its tender and frames are now sitting on No 7 road, with the Weltrol carrying Lucie moved to the south end. The boiler for Hartland has been delivered from South Devon, and is in the boiler shop where there is further work to be done by the MPD boiler smiths.

Wednesday 3rd October 2018

Yesterday at Grosmont was grey and cool first thing, but got milder later on with even a touch of sun. During the morning, Bill Dobson, Ian Pearson, Jon Bradley and myself gathered at Deviation Shed. First thing, Bill washed up all the dirty pots, some with cultures growing in them.Not a lot to do early on, so it was cups of tea all round and a gossip for a while. We found out from the shed staff that the Q6, which was on its way from Pickering with the teak set, was to be swapped with the Standard tank so that attention could be given to the repair of the L/H front valve cover and both piston packings which were leaking steam quite badly.

So we had an early lunch, and when the Q6 arrived on the pit outside Deviation Shed, we set about removing the valve cover and two oil pipes.

This took ages due to the fact it was very hot and the difficulties in finding the right size sockets. Ours turned out to be either AF or Metric, so we borrowed a 7/8 Whitworth  socket from  Andrew Jeffery. Our ratchet had also gone missing, so we borrowed one from William Parrish.

We do have some old box spanners which do fit, but they were awkward to use due to the limited access to get at the nuts. Eventually the cover was removed with a rope attached to the cover, supported by Bill above on front of the locomotive, then lowered to the ground. We found the copper sealing ring had broken. The cover was cleaned up pending NDT testing which was to be done today (Thursday).

Both sets of piston packings are to be replaced. The L/H side was dismantled by Bill to see if any of our old packings would do but they were too small. Owain was going to machine replacements from old BR standard packings today.  Barney gave us an assurance that both jobs - piston packing and valve cover - will be repaired by Friday afternoon and that the Q6 will be available for its booked turn on the LNERCA special train on Saturday.

Away from the Q6, Jon fitted two jubilee clips on the J27's steam brake lagging to make a more secure job.

 

Q6 returns to NYMR

Today the Q6 arrived back at New Bridge after its holiday on the Severn Valley Railway.

During Wednesday morning, Nigel Bill, Steve Hyman, Ian Pearson, Derek Shorten and myself, gathered at Deviation Shed. There was of course no Q6. I had called in at New Bridge on the way and found Allelys had just finished unloading the engine, and I was told that the tender had been loaded at the Severn Valley the previous tea time, and was expected by lunch time.

We agreed with Barney therefore that we would go back to New Bridge after an early lunch and wait for the tender's arrival and unloading, before setting to, joining the two together, and putting in a warming fire for overnight, before it reurned to Grosmont on Thursday. At Deviation Shed therefore, Derek kindly dealt with the washing up and made a pot of tea, and we sat and put the world to rights whilst watching the trains go by.

Lunch was taken on the picnic tables at Grosmont Station, and Nigel, Steve, Ian and I then made our way to New Bridge to await the arrival of the tender. That turned up within ten minutes of our arrival, but we had to wait about an hour for unloading to be completed and the wagon to clear the yard before we could get started. Having joined the engine and tender with the links, the locomotive was them moved on to the pit using the PW 08 diesel with Ian at the controls and Nigel as shunter. Once there, the hose was used to put sufficient water in the boiler, the guard irons were refitted and all the remaining connections completed.

The worst job was getting the sheets of plywood out of the coal shute in the tender. These had been put in to stop the coal falling out while it was being transported, but with the coal having been drawn forward, the boards were jammed in tight against the tender coal boards. Only by hammering these up were we able to, eventually, get the plywood out - and the coal duly poured forth all over the cab floor. There are also two long scratch marks down the left hand side of the tender as a result of a close brush with some vegetation at some stage of the journey.

Fortunately, they are not too deep and should be able to be rubbed out fairly easily.

However, Steve lit a warming fire and we left the site at 5.45. The Q6 was then returned to Grosmont the next day, with the smokebox now facing south, and on Friday was in traffic with the J27 for the first day of the Gala. It will continue in operation today and tomorrow, and will then be on the roster for service as required, along with the J27, until the end of the season.

While all this activity was underway at Pickering, Derek remained at Deviation Shed and cleaned the outside bench and the area around it, along with door to the shed.

No more working parties therefore for the moment, but if anyone wants to go down to Deviation Shed to do some cleaning, tidying and sorting, or just to watch the trains go by and chat to visitors, they will be most welcome.

In the meantime, many thanks to all those who have been down and working on the Q6 for the last 18 months. It has been a long time, but it made it in the end, and yesterday's photo of the J27 and Q6 double heading on the approach to New Bridge makes it all worthwhile.

Friday 14th September, Q6 enters traffic

Q6 working hard near Levisham on the 4pm from Pickering - Bill Dobson

Thursday's test run up the bank had to be aborted after a problem with the brakes. Today, after a light engine run up the bank and back during the morning, the Q6 was attached to the rear of the 14.30 departure from Grosmont to Pickering. All went well, so with Ian Pearson on the regulator it headed the 16.00 departure from Pickering. All bearings ran cool and the locomotive ran without problems.

On the Friday, the necessary work having been completed, Ian Pearson was the driver, and he managed a run up the bank to near Goathland in the morning. Again all was fine. It was therefore decided to put the Q6 on the back of the 1430 departure from Grosmont for a run to Pickering, with 76079 leading at the front (see photo). On arrival at Pickering, Ian reported again that following checks of the axleboxes and motion, all was well, and the Q6 then did all the work on the return journey, leading from the front, with 76079 reportedly making no contribution on the rear. The Q6 then retired back to the shed and was disposed with another clean bill of health.

The move to the Severn Valley for their Gala over the 20th - 23rd September was therefore confirmed, and today the Q6 ran light engine to New Bridge, Pickering, with Ian Pearson again driving and Richard de Sadeleer as his fireman. The opportunity was also taken to turn it on the Pickering turntable so the smokebox faces south once more (see photo). The engine and tender will be split tomorrow, and be collected by lorry on Monday. Barney Casey, the senior NYMR fitter will be accompanying the Q6 and will be able to fix any problems should they arise while the Q6 is away. It is then due back in the first couple of days of the week beginning 25 September so it will be available to star in the NYMR Gala on the 28th - 30th September, along with the J27.

Although, as a result, there will be no Q6 working party next Wednesday, there is clearing and tidying up to be done in Deviation Shed, and also a J27 to clean if it is not in service. So any volunteers wanting a day out in Grosmont on Wednesday will be very welcome.

 

Thursday 13th September 2018, Q6 meets J27

After disposal, the Q6 met the J27 in the running shed. The J27 had a warming fire for a post washout and repair steam test. This must be the first time that the two locomotives have met, in steam, and in the same BR livery, since the end of steam on BR.

However, such sights were at the end of a rather frustrating day.

Nigel Bill reports that he arrived Grosmont MPD with Terry Newman for an 8am sign on for a days running in on the Q6. The weather was glorious blue sky, sun shining, and a light breeze - perfect for running in trials.

He helped Terry prep the engine and do some cleaning whilst the MPD staff refitted the cylinder drain cocks and linkages. However, the front R/H drain cock in the steam chest could not be fitted tightly as the male to female connection threads were badly worn and would not seal. A temporary fix with wire fastening was done to allow some running in, so the locomotive was coaled and the tender filled with water before dropping down to Platform 4 at Grosmont around midday, with Adrian Dennis from the MPD on the footplate as fireman and travelling fitter, ready for a run to Goathland. However, the signalman only allowed 15 minutes in the section, so the run went up past Green End where there was a stop for a check round. No signs of anything running hot or squealing out for required lubrication, so it returned to Grosmont Station where the engine was checked again and nothing untoward was found.

They were then given 40 minutes in section to get some further running in done, but when Terry opened the regulator to set off, the engine would not budge either in reverse or forwards - fighting to the end!

Adrian and Terry set about identifying the fault which was found to be the steam brake not releasing the brakes: nor would it with the ejector.

The locomotive steam brake piston had bottomed out on the cylinder, and would not release as the linkage had gone past the vertical and could not be released by steam. Adrian had to get his bag of tools out therefore, and set about resetting the linkage which allowed the brakes to release. It was then decided to return to the shed as a R/H side drain cock was blowing by. Back on shed, it was found the drain cock that had the temporary fix had failed to hold in the Station whilst the regulator had been opened and shut a few times to try and get the engine moving before the brake fault was found.

As a consequence, it was decided to call it a day, as a permanent repair was required for the drain cock and the brake linkages could be adjusted to prevent the piston sticking at the bottom of the cylinder. So, after 2 days of trying to get miles under her belt it was reckoned that about 4 had been achieved. Not what had been expected, and the shed staff were left with work to do on the Friday morning to hopefully enable some more running in to be done.

The day's events were also filmed by the Channel 5 documentary team, including interviews with Terry, so the day of frustration should appear in the new series when it is aired next year.

 

Wednesday 12th September 2018

A bright and breezy day at Grosmont yesterday, with Nigel Bill, Bill Dobson, Ian Pearson, Nigel Hall and myself, along with a Q6 raising steam outside the MPD on No 5 road, prior to moving to the coaling plant pit under its own power for the first time in 18 months.

Q6 on No 1 road pit at Grosmont for drain cock removal - Chris Lawson

Here it was oiled up, a replacement front shackle found for the one that was missing, and Nigel Bill went over to Teesside to fetch some sealing rope for the smokebox door. Meanwhile the MPD staff were wrestling with a leaking vacuum, fitted the smokebox door seal, and completed a number of other small jobs before we broke for lunch. The previously welded bracket on the fall plate was then found to be broken again and was rewelded, but this will be only a temporary fix as the fall plate itself is badly twisted and will need to be replaced. The injectors were tested and were working fine, but as the locomotive was put into reverse to move up the headshunt for some running in (it is currently smokebox facing north), the isolater valve on the reverser pipework between the frames fractured. Quick work by the shed fitters saw the multi union pipework replaced, along with the now redundant isolater valve, and the original pipework run restored after it had been annealed. Moving the engine then revealed that the drain cocks were not working as they were full of dirt, so the Q6 was moved down to the pit on No 1 road for the drain cocks to be removed (see photo). That done, the engine then finally did some running up and down the yard for about an hour with Ian Pearson driving and Nigel Bill on the shovel (see photos), before the day was finally drawn to a close with tea and cake, and the engine disposed. All the axleboxes remained cool.

Q6 on the move, without drain cocks! Deviation Shed, Grosmont - Nigel Hall.

Today (Thursday 13th), the plan is, first thing, for the drain cocks to be cleaned and replaced, along with the vacuum diaphragm in the hope that this will cure the leak. The Q6 will then spend the day running up and down the bank with Terry Newman driving. If that goes without problem, it will then spend tomorrow running to Pickering on the back of service trains, and, if that is OK, Saturday will see it on the front of service trains, with the aim of getting about 200 miles of running in successfully completed. Assuming all goes well, Sunday will see it at New Bridge, Pickering for splitting the engine and tender, ready for loading first thing on Monday morning for the move to the Severn Valley for their Gala at the following weekend. If it goes, and it is still an if, then Barney Casey, the senior fitter at the MPD, will be going with the Q6 to make sure all is well, and that if any problems arise, they are dealt with.

Q6 at Deviation Shed during first running in - Chris Lawson

It will then return in the week beginning 24 September, ready for the NYMR's own Gala over the final weekend of the month. This should see both the Q6 and J27 in action.
