Saturday 3 September 2011

The plan for the day was very simple... it was to compete all outstanding tasks to ensure that 6029 could be safely shunted. So we started off in the smoke box as the forty 7/8 BSW bolts had to be fitted to secure the boiler in place. The problem is that all of theses holes had been welded up when the boiler was used in stationary service. As fast as we were trying to drill out the holes the drill bits would become blunt and useless. Solution, get a bigger drill, use plenty of cutting fluid and keep sharpening the drills. By lunch time we had roughed out about 12 holes and we had had enough, so our next workday will involve a very large air drill and maybe some colorful language.

Mark and Alan started the fit up of the air compressor's Nathan mechanical lubricator and associate pipe work. Tony continued to dot around the locomotive with black paint as it seems we had missed few spots, it is over 100 feet long!

Back at the cab end Graeme Kidgell completed the installation of the fireman’s side boiler feed lines. Andy Heys prepped the last of the cab mounting bolt holes and also had time to sneak in a few cups of tea. You just cant get good help theses days!

By days end we received news that the Eveleigh team had almost finished the cab and that one more day should do it.



All being well the cab will be back in Canberra before then end of the month and will go straight onto the locomotive. Updates will be posted as the details firm up.

The day started with the usual time honored cup of tea and a chat. The completed cross compound compressor was on site as it had been delivered during the previous week and the first job for the day was to fit it to the smoke box. Once bolted down the associated pipes were hooked up including the governor and lubrication piping.



The two main reservoirs were offered up and fixed in place with the retaining straps. Sounds easy to say in one sentence but the alignment and fitting of the pipe work was no easy task. Anyone would think that we are getting good at this type of thing. The outstanding smaller valves such as the independent release valve were fitted into place and as the main reservoirs were now fitted we are basically done with the brakes. The only outstanding task will be the fitting of the three and four control pipes that run from the drivers brake valve to the distributing valve. These pipes cannot be fitted until the cab is in place.

The trailing pivot nuts were adjusted/backed off and after the usual three man pull helped by a four foot long extension bar, the unit settled down into position. The constant contact side bearings were checked for alignment and all was well. As we had a good turnout of volunteers we were able to also have another look at the stoker trough and it was decided to remove the two leading support brackets. As originally fitted they were held in with bolts however, later in life they are welded into place. That’s OK in service but it prevents the stoker trough from being removed as designed. The use of an angle grinder and about six cutting discs later and both brackets were removed. The fork lift made easy work to slide the trough out and as suspected it will require a full rebuild.

To say that we had a significant workday would be an understatement as we completed a few milestones that are noteworthy in context to the overall project. These being the completion of the brake system, the removal of the stoker trough and the adjustment of the pivots. Having completed these tasks the locomotive can now again be shunted safely. From a strategic overview there are no more strip and assessment tasks to complete. In essence we are putting 6029 back together and we hare now planning for the steam testing and subsequent operational systems checking. To this end the hind bunker/tank has be fitted to facilitate the up coming steam tests later this year. However we have a lot to do before this can take place... for instance the ash pan and fire grates still have to be rebuilt and the smoke box fit out will be the next major tasks. We still have to fit 20 superheater elements, the blast pipe, main steam lines and the front end throttle assembly.

Restoration in the open!

Just in case you thought that we always had it good here in Canberra, take a look at these two panoramas of our outdoor resto's. Its cold and the rain was about to set in and stop work.



6029 is coming along very nicely, and will soon be moved undercover to have some of the finer work completed. We are all looking forward to having a roof over our heads, with a dry environment free of rain and sunburn after 5 years in the open. In truth, we have had a really good run, with very few workdays called off due to bad weather, but with the drought over and summer coming, that may all change.


4468 however will have to remain out doors for a while longer. You can see from the picture, that there has been a lot of work done already on removing and controlling corrosion in the frames that support the body, but there is still a lot to do. Note that the shop bogies look so wrong under a large diesel... In their past life they were under a 30 class tender.

As the weather forecast wasn’t that promising, the team got off to an early start. Paul Nowland fitted up both the brakestands with the overhauled valves. While in this area, Tony fitted the new driver's side sub floor ably assisted by Paul. This is a two man job with Tony inserting the bolts on the top side and Paul tightening up the nuts on the bottom side, or was it the other way round?

Graeme Kidgell continued with the drivers side injector feed pipe system, working through to the steam starting valve adjacent to the outer firebox wrapper. The last pipe that joins the steam manifold to the injector starting valve was trial fitted and to no surprise, wasn’t even close. After a few goes at heating the pipe with the oxy it was decided that it would be replaced and in actual fact the pipe was found to be suffering from fatigue cracks. For safety reasons both the drivers and fireman’s side pipes will be replaced with new.

Just before lunch the team moved onto the final adjustment of the leading pivot and the new 3 ½ inch AF socket, and inch drive ratchet made this labour intensive job slightly easier. Well only just. The adjusting nuts were backed off and re-set. The next task will be to fit the pivot locking plate with four off 1 1/8” BSW nuts.

While the crew stopped for lunch the rain started coming down and a couple of morning showers soon turned into constant deluge. At 14:00 hours it was decide to call it a day and go home to a hot cup of tea.

The Air Compressor

Alan Gardner has been quietly working away on the Garratt's cross compound air compressor for a while now, with little bits being ordered here and there as money has become available. Some time ago the piston rods were hard chromed by Diamond Hard chrome in Sydney, and the castings were all sent to Melbourne specialist, Laurie Cameron from East Australian Engineering, where they were given a top notch overhaul. The bores were accurately re-machined and measured before being kindly returned to us by PBR member, Graham Clark on a trailer.

Just recently the new rings were ordered and that has allowed him to begin the reassembly in his spare time, and as you can see in the pictures, it is almost complete and looking very, very good. Now he is only waiting on some new gaskets, before it gets tested on air and refitted to the loco...



With stuff like this happening, you can really see the loco returning to steam in the not too distant future.

The brake system rebuild continued today with work on the main reservoir piping. This included the one inch steel pipes that deliver compressed air from the main reservoirs to the brake stand and the distributing valve. Most of the pipes are in good condition and they only required a clean up and a coat of paint. One small section of pipe that is about 2 foot long is missing and if we cant find it we will make it new... Murphy's law will ensure that the missing pipe will re surface once the job is done.

Andy continued with the fitting out of the large bore injector feed pipes and by days end all of the drives side was completed and looking like new. Tony cleaned up the water balance pipe isolating vale and associated fittings. The only outstanding large bore pipe on the drivers side pipe is the feed lines from the injector to the clack vales on the top of the boiler.

The stoker trough that is attached under the coal bunker is in very poor condition and will required a complete rebuild. Most of the afternoon was dedicated to extracting the 24 one inch BSW bolts that attach the front of the stoker trough to the coal bunker. No amount of force would remove them so the oxy torch was deployed and about two hours later the team tried to drop out the assembly. Despite our best efforts it resisted and with the fading light, it was decided to make a tactical retreat and leave it until the next work day.



Another project going on behind the scenes is the overhaul of the Westinghouse cross compound air compressor. It was stripped down and assessed in 2009 and although in reasonable condition it was decided to give this vital piece of equipment the gold plate(aka Rolls Royce) treatment. Since then, the piston rods have been hard chromed and ground to size. The cylinder assembly and shuttle valve head were sent to a specialist contractor and line bored back to specification, and a complete set of piston rings was recently delivered and fitted with excellent results. The pistons now move up and down the bores with a good running seal.



New gaskets have been ordered and when delivered they will be fitted in no time. That will leave only an air function test before fitting the complete unit to the smoke box.

The brake system rebuild is progressing as a high priority. The distributing valve has been fitted up to the auxiliary/relay chamber followed by the dead engine isolating cock. The 3 & 4 independent brake control pipes that run from the distributing vale to the cab were found to be in poor condition and will have to be replaced.

In general terms the brake system rebuild is almost complete with only a few pipes still to be refitted. The project manager spent most of the day tracing pipes under the cab floor. Not any easy task as this space is fast filling up. Paul Nowland has been working at home on the automatic, independent brake valves and the feed valves. Thanks to Paul the brake system rebuild has progressed at a fast pace.



The two main reservoirs have been passed by the boiler inspector and will be fitted into place shortly. Once the reservoirs are in place, the system will be charged up and testing will follow soon after.

As the cab floor is not yet in place and access is readily available, the six inch water feed pipes and elbows that run under the foot plate have been refitted and the painters have finished off the area before the floor is fitted. The new replacement sub floor plate was painted and the mounting brackets for the equalising reservoir were fitted ready for final assembly.

Graeme Kidgell continued to fit up the boiler feed pipes and the injectors including the associated handles that control the water flow. The boiler feed pipes are very large, heavy and awkward to fit, in some cases it requires four people to persuade the pipes into their proper position.



In terms of the projects critical path, we are working hard to complete the tasks that will enable us steam test the boiler in the near future. This includes, but is not limited to, the injectors and their pipe work, safety valves(rebuilt but not fitted), fire grate, ash pan and finishing the smoke box fit out. We will also look at the stoker trough in the coal bunker as this has renewed and refitted before we can fit the coal bunker/water tank.

While all of this has been happening, you can see from some of Howard Moffat's photo's, that progress is also being made on other locos in the fleet. Work continues on 4468's body frame repairs, the cab of 4807 has received some attention and a few mucked in and got stuck into the brakes on 3016...

Once again we started of the day with sub zero temperatures but it wasn’t long before the thermometer soared to a massive 2 deg C. Yes as usual a cup of tea and hard work would soon warm everyone up.

Work continued around the driver’s side cab sub floor and associated brake systems. The new floor has been pilot drilled (small holes) and checked for fit and alignment. The floor sheet was lifted off to allow the welding of the sub floor support bracing. Graeme Kidgell welded the bracing to the boiler cradle main cross member in no time. This is bracing supports the sub floor and rear cab sheet. Graeme then turned his attention the brake stand support bracket with the fitting of the horizontal six 7/8 BSW bolts. The brake stand was next and the end result speaks for it self. Tony was next with the usual wire brush clean up and grey primer.



Back at the floor sheet David opened up the pilot holes to ½ inch and cleaned up all of the sharp burs and edges that were previously oxy cut. The old angle iron that supports one side of the sheet was welded in lieu of rivets.

As we are starting to put the brake system back together, Kyle and John were tasked with fitting the relay chamber to its support brackets located near the smoke box on the drivers side. After some initial problems it was discovered that the support brackets were in place upside down. Yes the project manager fitted them a while back, oh well you can’t get good help these days. After the brackets were re fitted the correct way up the chamber fitted with ease. The two inch diameter brake and brake cylinder pipes were fitted with only 3 or 4 control pipes to go. If we can find them amongst the tons of stored small bore copper pipes.

After lunch the team started to sort through the bundles of stored pipes starting with the injector and feed system. The fireman’s side injector had to be fitted first as the pipes have to attach to something in the first instance. Graeme has many years of experience behind him when he was working for Puffing Billy Railway in Melbourne. By his own admission the injectors on the 60 class are a tad bigger.

The front tank has been lifted off to allow the final fit of the steam pipes and sand boxes. This will also make it easer to fit the remaining super heater elements. This can be done with the tank on but having the tank off expedites an awkward job. The fireman side sand box resisted but eventually yielded for final fit. The leading steam ball joint was lifted in to place just ahead of the smoke box. We only have ten feet of steam pipe to fit and the leading unit steam piping will be finished.

The last of the top coats of black paint were applied to the top half of the hind engine unit with very pleasing results. The entire locomotive is looking almost like ex-works condition and in fact even better. The team also took time to clean down and paint the newly installed buffers. So in essence we have been from front to back in just four short years. Pity about all those bits in the middle. Now that we are again in the middle(the boiler cradle) the new drivers side cab sub floor was pre drilled using the old section as a template. A trial fit confirmed all was well and about 30 half inch holes where drill through ready for final fitting.

The brake systems rebuild was helped along with the final fitting of the flexible pipes that bridge from the engine units to the cradle. It was good to see the old replaced with new without compromise to historical design. Not much has changed in 60 years with regard to flexible hoses. The drivers side brake stand has been completely rebuilt with all new copper pipes and fittings including all four feed valves. Paul Nowland continued with the rebuild of the automatic and independent brake valves.

Gavin and new mate Tristan installed four more super heater elements. Probably not the best initiation but at least we only have sixteen to go! More tee bolts will need to be sourced before we can complete the element installation.

Cab Progress in May

It has been a while since I have updated you on the cab and its progress at Eveleigh.

Overall, the cab looks again like the cab that came off the Garratt a while back, with the notable exception of the corrosion that was present in the panels and frames. I would estimate that at least 25% of the cab has been replaced just to repair the damage caused by all those years of exposure.



The majority of the riveting is done, with the exception of 4 lines of rivets that could not be completed until the roof is properly attached. One more day with the team from Goodwin-Alco will see that all completed.

The last workday saw the roof more or less completed, with just a little welding to be completed and one small panel to be cut and fitted. The roof is all new, and is completely devoid of the holes that caused the ultimate demise of the original unit. All attachments are now internal and with new hatches that are stronger and easier to use, the cab should be a nice place to work. As part of the work, we have also added proper lifting points to allow damage free lifting of the cab from the frames and the roof from the cab in the future, a small detail, but one that will be appreciated when we have to do any heavy maintenance on the boiler or mechanical stoker.

There is some detail work to be completed, like new window frames in the rear of the cab, but there is most certainly light at the end of this tunnel!
