It certainly will help remove any existing rust, and presumably(?) any residue will not of itself cause rusting as other acids tend to. So perhaps phosphoric acid fluxes are a good choice for soldering steel rail.

No, it is a rust convertor and if it is not immediately washed off and dried and over-coated, the rust will reform. For confirmation of this, have a look at the instructions on a bottle of "Jenolite"!!
BTW, if anyone wants to see steel rail rusting, just leave a length lying on the bench whilst you solder-up an etched brass kit! The splashes of flux will soon make themselves apparent. I only know this because the usually excellent chaps at C&L accidentally packed a length in with some proper rail I bought
Unfortunately, the stuff does the same for steel tools as well if care is not taken - what a good job that the rail which other people buy is made of a completely rust-proof steel.

I have actually made some significant progress over the last few days. I have rail, NS, but no more check rail chairs. Undaunted I perched the whole layout on my workbench and made some inroads into the 3 way.
As you can see from the turnout it seems to be fitting together rather well. I always start a turnout with the intention of building it 'by the book' but get distracted early on. Maybe that's why my track work has a rustic feel to it. The excuse here is that Drakelow is a learning layout. I am bound to make errors in construction but thus far I'm very pleased. My crossing filing seems quite accurate. I do things by eye generally, then check with gauges, then admire the successes...... or rework the failures.
I've started the 3 way by laying the inside curve first and moved outwards and carefully thought about the placing of chairs on the interlaced sleepers. The test wagon goes through without (much of) a fuss. It's a rigid chassis so compensated stock should have no trouble.

Re: Drakelow
Hi
I have used Jenolite for years in car restoration. Most rust removers will convert the rust but only on the surface, Kurust for instance, I have often left the rusted component to soak in jenolite for a couple od days before wiping and drying it off. I have two spacers which were de-rusted in jenolite this way 10 ears ago and are only now showing a couple of small rust spots.
I have not tried it as a flux, interesting idea for steel rail, will give it a go in the future

Most 'rigid' P4 wagons aren't actually truly rigid. The axles can move sideways by a small amount, within the coning of the bearings, which allows them to adjust to minor irregularities. The dynamics of compensated wagons are different, and also may differ depending on whether the fixed end or the compensated end is leading (which is why many preferred springing once the parts became available). You may find it helpful to test points with a compensated vehicle as well.

Re: Drakelow
Agree with Jim, rust in the wrong place (on the running surface) will play havoc with smooth running. Have you travelled in the first train of the season on a preserved line, when the rust gets knocked off, it's very noisy. In 4mm, we don't have the mass to clean the rail surface.

Jenolite is, I believe two thirds phosphoric acid, which is the basis for some fluxes. I used it quite successfully as a flux for many years when I was poorer. The danger was it tasted much like a well known brand of Cola Drink!

Re: Drakelow
Whilst making outline plans to think about doing something to Drakelow I came across some supplies lurking in the lower recesses of my workbench. They comprised of 200 sleepers and some turnout timbering, the C&L thick variety. Incompatible with the sleepers I've used on Drakelow, (0.8mm ply,) I decided to have a plank day using them up on a quick two turnout Templot plan and an cut down baseboard.
This baseboard was originally 1150 x 400, the same dimensions as the Drakelow board. It was cut into two 1150 x 200 boards to sit in my workroom and tempt me into using them. As the day progressed and I had little interruption and I made good progress. I'm actually amazed that it went together so well (so far).
I have christened this plank "Enville" after the small village in South Staffs, just a few miles from Drakelow. Luckily there is a suitable real location for this conveniently spied on Google Earth and is now being imaginatively interlinked into the Drakelow history.
There's nothing to say you can't have 2 SGW projects is there?

Hi Ian,
Essentially it is two turnouts of the same hand reversed and interlaced.
So called (on the GWR at least) because they were common in the sorting sidings at Barry Docks.
And now we have the evidence -- a ladder of Barry slips at Barry:
Many thanks to Sandy Croall for the pic.

I'm pretty sure these "Barry Slips" were not at Barry.
This photograph appears on page 51 in John Hutton's "The Newport Docks & Railway Company" published by Silver Link Publishing Ltd in 1996 (ISBN 1857940873). It is credited to Associated British Ports and the caption reads "Coal for shipment circa 1930 shown here at the Tredegar Park Sidings, one of the Alexandra Docks numerous yards. The wagons bearing the initials 'EV' are from Ebbw Vale collieries, while those marked JL are from John Lancaster Company, which had collieries at Blaina, Cwmtillery and Griffin."
I suspect that the PT wagons may have been from the Powell's Tillery Steam Coal Co. Ltd.

If you have the 2002 edition [ISBN 1 85794 163 2] it's on p112. The AND&R also had similar ladders in Monmouthshire Bank and Mendalgief Bank sidings at the entrance to the docks. Indeed, given the resemblance of the distant northlight building centre right to Newport Pill shed, I wonder if the caption is possibly wrong, and this is actually the north side of Monmouthshire Bank looking South West, before the Whitehead steel works was extended?
Incidentally, it looks as if the track is fairly lightweight flat bottom, spiked to the sleepers?

Re: Drakelow
Iain Rice wrote at some length about making you own phosphoric acid fluxes back in the late 80's in 'Model Railways'.
On a suggestion from a colleague in the Science Dept. I have tried cleaning flux off steel rail with meths applied vigorously with a stiff hogs hair paintbrush. After a fortnight I can report no sign of rusting. I don't claim to say this is the solution to rusting rails after soldering, but it might be worth a go.

Re: Drakelow
Those are too easy. Mine is on a curve.
This is a version I built some years ago for an O gauge light railway. I used Code 82 FB as I recall which was way too small in section for O gauge wheels. The inspiration was Chichester station on the Selsey Tramway

Re: Drakelow
A bit of slow progress has seen some more track be laid, and some that needs to be lifted. I laid the dairy siding with C&L flexi only to find it had gone out of gauge somehow. No amount of coaxing will get the rails apart, at least not without damaging it. So back to plan A, rip it up, all 17" of it and relay with ply sleepers. At least I can get the 3 point gauge on it for some widening.

Re: Drakelow
Hello Bunchie3174,
What sort of glue did you use where the C and L flexi track was laid? And did you spread the glue evenly over the entire sleeper area? The thin plastic sleepers of this track can bend up slightly if not glued properly and cause gauge narrowing. I've used a lot of this track on my layout, including curves, without problems. I use PVA glue, thinly and evenly spread over the whole piece of cork underlay where the track will go and then carefully weighted it all with books or something similar. Make sure you leave it to dry thoroughly before removing the weights. Curiously, C and L flexi track is just a tad narrow on gauge when measured with a P4 roller gauge, which obviously doesn't help matters, especially on curves. Also have you tried any rolling stock through the three way point yet? The reason I ask is because the crossing vees seem to have quite wide gaps which could cause derailments; it might just be the way the first photo was taken though.

Re: Drakelow
I gave up on the C&L track on anything other than very large radius curves a long time ago as it always gave trouble, in spite of following Simon's glueing technique. Its a good timesaver for straight track but all my curves are now on ply.

I think part of the problem is that the plastic is quite soft and there is sideways play/movement in the chairs when it's curved causing the angle of the rail to change.

Re: Drakelow
Hi
Going back to your battery powered loco's, you could always have a section of track powered as charging track, then just park the loco over it for a few mins between moves.
These radio controlled helicopters etc, have the charging circuits built in to them, and take up very little space.

Re: Drakelow
The offending section has now been removed and will be relaid shortly. It was glued down with PVA aand weighted as you method. There was an odd section of about 1" that was undergauge, about 18.4mm, the rest was within tolerance. I had removed all the web from between the sleepers so it matched the Templot plan. I'm not sure if that would make a difference.
The 3 way is working well in terms of the stock I have to test it with, whether that will be the case later on, I don't know. The flange ways were checked with a society gauge so they must be right, or very near to.
The battery powered loco project is coming along slowly. I have assembled the Deltang Tx 12 channel kit and attached an Rx to a spare chassis (OO) to test. I'm hoping to implement it in a Hornby Cl25 once it's rewheeled. Currently I'm trying different battery options. LiPo seems the best way forward providing you have a suitable charger. I would remove the battery to charge until I'm sure I wouldn't melt the loco. I'm not that lucky to avoid a mishap like that. Finding LiPo battery packs which will fit is another matter.
It's all part of the joyous P4 learning curve so I appreciate your responses.

Re: Drakelow
An update on progress on Drakelow.
I've tried and tried to get wagons to run through the 3way but I'm not having much luck, I think because of the tight curvature. I'm going to take it up and start again.
I've been busy helping a friend make track for his layout but neglected my own projects. During this process I've gained some useful experience in turnout construction. (His layout is 00-sf but built with C&L components).
While I was thinking about it I found another section of board which I thought could extend the layout somewhat.
Basically I'm adding an L shape to the end of the layout in order to have a bigger fiddle yard/sector plate. The upshot is that the length of Drakelow will be extended from 1150mm to 1750mm. 600mm extra, of which 400mm will form the fiddle yard and 200mm will extend the scenic section.
The overall track plan will remain the same apart from the removal of the 3 way and the addition of a loco spur on the kick back siding. Due to the extra length I have made all the turnouts (bar one B5.5) B7 and lessened the radius of the curves. This should improve running.
I've got a few weeks off work with a broken hip so i should be able to make some progress, or go mad trying.
