Track laying on TT2 progress

Postby Captain Kernow » Sat Sep 05, 2009 7:32 pm

DRAG had another Saturday meet-up at Holcombe village hall, near Teignmouth today, with the objective of sorting out the baseboard levels/leg & feet adjustment on the hall floor and laying some track:

The various configurations of point work laid out, ready for laying in position on TT2. These range from A5 to D12, so that a variety of stock can be tested on different radii of trackwork

All boards now erected. The whole circuit is very stable when fully put up and bolted together

After lunch (in the pub opposite the village hall), some useful time was spent transferring the key dimensions of the full sized Templot plan onto the cork surface of the baseboards, with 'running edges' drawn in, in ink, for the track layers to follow.

A C8 also glued in place, which will form the entrance to one of the loops off the Down Slow line. The white area under the point is a 15 thou plasticard 'template', which brings the top of the rail on the copperclad points up to the right level to match with Exactoscale Fasttrack. Despite scouring Brian Lewis' stand at various shows, we were unable to find a thickness of copper clad sleeper that precisely matched what we needed. As it's essentially a non-scenic test track, we are content to solder the rails direct to the sleepers.

Just to add to CK's excellent photos, much good work in marking out was done by David, Graham, Pete and myself using a mix of Templot, cotton, straight edges and a set of railway curves fortunately rescued from a skip by David when his employer's drawing office went metric and computerised.

Also here is the cutting of tracks laid across a board junction and the 'packing' needed to get rail heights equal with different modes of construction.

I'd be interested in any comments on whether a facility like this would actually get much use if it attended an exhibition. We are aware of interest for Scaleforum sometime, but my experience of test tracks in the past is they take up a lot of room for not a great deal of benefit. How many would bring stock to run on it for example?

Mmm "The Flood Tide"...,never read it; is it any good or just ballast? Nice track though.

Further progress. All the track has now been laid on one of the straight sides, except at the ends where the transitions into the curves start. This includes the 00/P87 inner track - because it's a test track we haven't attempted to 'improve' the appearance of the Code 75 Peco, but once again the contrast highlights much of what P4 is all about.

Now it's the other side - where there's a lot more crossovers!

In a tightly focussed session today at John Farmer's house in Kingswear, we made a very good start on the other side of straight boards.

Due to space constraints, we could only set four of the five up, but this did not matter, because we were able to get all the remaining point work laid, bar one C8 turnout into one of the running loops, which has to go on the 5th straight board.

Here is progress towards the end of the afternoon, when I was called away back home to attend to my better half on her sickbed:

I think that I am right in saying that the vessel is a Type 42 Destroyer.

Nice to see the track progressing.

Hi Rod

We attended several scaleforum's with the WMAG test track and had a steady stream of cusomers on both days. However a lot of people used the test track as just that - a test track for a final shakedown before entering their locomotives into the Deputy Chairmans Cup. Without the DCC I dont know what the patronage would be like. Speaking of DCC (see what I did there?) I assume you are going to supply DCC and DC options?

You will need to bring a supply of loco's too as while a lot of items are brought for test are locomotives, a lot of people will bring along stock only.

HTH

Jim

(AFAIK the presence of out test track was the only time a P4 APT ran at scaleforum. It was also AFAIK the first time a P4 HST ran too!)

Yes, it will have interchangable facilities.

Hi John

By interchangeable do you mean the layout can be DC or DCC or do you mean tracks can be DC or DCC? For a public test track it will need to be interchangeable by track not as whole.

Cheers

Jim

Hi Jim

As you see there are four basic P4 circuits, of which the outer one has storage loops on each side. There is no physical connection between the outer and inner pairs. The idea is that either of the two pairs of P4 circuits can be switched to operate under DC or DCC, so both can be available simultaneously. The inner 00/P87 circuit will also be switchable.

Amazing work! I really love the look of the D12 crossover.

Do you have a method of point operation in mind?

Thanks Matt (and hello stranger, you've been away a while!)

Some form of very simple wire-in-tube buried in the trackbed I think - we'll put more info up when confirmed.

Some of you may be wondering if we've all been on strike or something recently. Not so, work has been progressing steadily behind the scenes, at DRAG meetings and particularly at John's (Re6/6) house where he can get on with it unencumbered by distractions and ribald comments emanating from the rest of us.

So, here we have some recent photos showing developments on the curved boards - note the superelevation applied to the middle two P4 tracks (up and down fast) using the Tillig polystyrene wedge thingies; the protective plastic upstandings on the board edges; and the overall red oxide colour applied to make the whole thing look a bit smarter than just having MDF/cork/PVA etc showing. These are the same photos as on the blog on RMWeb, but I have tried to tone down the fuchsia pink colour caused by John's camera shooting indoors - I haven't seen the real thing myself yet, so only he will know if I've got close.
