That point at the entrance to the reverse loop looks interesting, Greg. Scratchbuilt?

Rik
Thanks Rod and Rik.


Yes that was my first scratchbuilt turnout. I could only buy some "O" gauge rail at the time, so used the 'old' copper clad board method from HO days. (all the old track power wiring is still in place!)

You may be alluding to the 'funny' guard rails at the entrance to the turnout. They were the solution to the fact I didn't allow enough clearance as is this pic. I could have resoldered the moving rail, but chose this simpler method. (It's a recurring problem even with turnouts I make these days - some people never learn!)

and now the next exciting episode of my maintenance.
How come that for every job I do, I find another two????

While leveling the 4 parallel tracks at Sandstone, I noticed that the left end of the platform had sunk (I sometimes step on it, and it's just a piece of 2" thick Hebel.)
And the track had buckled up due to expansion. The result was a platform almost at ground level.
DSCN1937.JPG

The main problem is that in front of the building the track must be level, but at the left end the track height is fixed by the big sandstone ledge. So that 2' length of platform has to be on a grade.
So I reduced the rail lengths by 3mm to allow expansion, did some 'horrible' vertical bending of the track to accommodate the two grade changes. Then dug up the platform and raised it. And repainted it all with oxides mixed with water. I also repaired and painted the fences. Here's the result
DSCN1940.JPG
and the overall view.
DSCN1948.JPG


Then while running a test train for the platform, I had a derailment on one of my concrete path crossings. I have 6 crossings. The earlier ones (c. 1995) are my aluminium bar rails in slotted wooden sleepers, covered in concrete.
But now I notice that the concrete over the sleepers has broken and the sleepers rotted so the track is under gauge. I'm not going to rip them up!!!
So as a start, on the worst crossing, I made some aluminium 45mm spacers to temporarily hold the rails at gauge, then used pure cement (no sand) to fill between the rails up to 3mm below rail tops.
You can see here..

before   and after comp.jpg
I only did half the crossing and will wait for summer weather to test the conc strength before I do the other crossings.

And if you look at the top of the left pic you can see the timber crib wall. And guess what? It's rotten and falling apart, so watch for the next installment on repairing it.

Would you believe the official name of the colour I use is "Sandstone" !!

Very smart, Greg. Something which rarely seems to be covered in posts is general maintenance, but it's something we all have to engage in constantly. Maybe you've started a trend?

I don't know if it will start a trend. We all seem to enjoy reading about new builds. BUT since I am not building anything new, all I can offer is the maintenance work.

Certainly interesting, nevertheless. I'm looking forward to seeing more, as and when it happens. It's a bit like seeing those videos on Youtube, wherein some old object, tool or machine is fully restored - we get to see the repairs and improvements, without the chore and drudgery of actually doing the work! :roll:

As mentioned in my last post, the crib wall along Maple Jn is made from treated pine 2"x1"x1/4", the same wood I use for my sleepers.
I built it in 2006 but now it is starting to rot. Virtually impossible to replace individual 'slats' as they are nailed together, one above the other.

This shows the problem.
before1.JPG


I decided to just fill in between all the slats with concrete, hoping that will extend its life by 10 years or so.
I lifted the track in front (coal loader siding) to allow easier access. I coloured the concrete with brown oxide and left the slats sticking out by 1/2" or so to keep the crib look.
Here's a closeup
partdone1.JPG


The siding also had many rotten sleepers, so I replaced a few - just enough to hold in gauge. I will then concrete the whole track in. As it is an 'industrial' siding I figure covering all the sleepers almost up to rail top will look prototypical enough. This has not been done yet due to bad weather.

Sounds and looks like a really effective repair, Greg. Fingers crossed for the next ten years.

This next job wasn't even on the list of things to do, but many derailments forced me into it.
The first bit of track I laid back in 1994 was to get through the wall of my train room and across the concrete ramp just outside. The ramp is on a 1:5 grade!
I was using 3x12mm aluminium bar rail in timber sleepers . I covered the whole track across the path with concrete.
This is the 'now' picture. The concrete has cracked and exposed the sleepers which have rotted away. You can see some unsuccessful attempts to repair the track gauge with silicone and Builders Bog.
before1.JPG

And this is the piece of track from the path to the wall on a steel channel. You notice I put many electrical wire in the path crossing as I was using track power and I allowed plenty for future needs.
before3.JPG

So it was out with the hammer and chisel and rip it up!
I also had to replace about 3' of track adjacent to the concrete where I had used old Aristo plastic sleepers-they had disintegrated in the sun!
aristo track.JPG

So the 4' path crossing finished up needing about 12' of track replaced.
For the concrete buried track I used copper-clad PCB board soldered under the brass rails at about 6" spacing and timber sleepers/steel nails for the rest.
This pic shows the track in place before concreting.

Now to wait for a few fine days to do the concreting.

The amount of track maintenance can get out of hand it seems Greg. I must admit I haven't given it much thought on how much work would be needed to repair track. Then the heat from the sun is considerably hotter and a lot more fierce I would imagine in Aus. But that's not to say we Northern Hemisphere people have our own problems also with weather.

Thank you Greg on another interesting thread ...
