A 30 year dream becomes reality

blog-0396980001370212239.jpgStimulated by seeing the layout by Robin Whittle and the Glevum group at Scalefour North, I came home and dusted off the papers, maps, plans and photos built up over 30 years for the time when '75A' would come to life... that time, I have decided, has come!

I was impressed by Chris' (??) baseboards. He took the time and trouble to describe to me the construction of the baseboards which he produced. He uses 6mm beech ply in two laminated layers to construct the edges of the board, the inner layer being recessed to take a single 6mm sheet for the trackbed. The resulting box is strengthened by intermediate members but no diagonals. Up to now I have used a geodesic plan based on 9mm plywood, but I have decided to give Chris' method a go for 75A.

 

OK, so what's the plot? Well, Templot, actually. There's no way I could achieve the required diagram without it. Yes, it's a devil of a learning curve and I still only know about 1% of it, but for anything approaching realism, I can't imagine a simpler and more reliable way of planning such a complex track layout. I still think that Martin Wynne studied at Hogwarts!

 

Unfortunately, copyright laws prevent me from showing the Ordnance Survey map (which I bought!!) at 1:2500 which shows the 1956 track plan in enough detail for effective use. I used it in Templot as a background image and am midway through version 3.0. Why version 3? Because I'm still learning! Templot is very flexible and you can go back and revise, correct and amend and that's what I've done. The templates are still far from perfect but they will be refined over time. I have attached the current track plan from Templot to show the extent of the layout. blogentry-0-0-93809200-1370211308.png

 

The baseboards (as currently envisaged) are shown in red outline. I say "currently envisaged" as these are very irregular shaped boards and joining them together is an important consideration for e.g. exhibitions. The location of track, point motors etc will have a dependency that results in the final shape. Not being a carpenter my results won't be nearly as neat as Chris'. As with Barrow Road, I hope to have the first two boards in place very soon and these (the East sidings) can provide some running without the other boards being finished.

 

I have plenty of photos of 75A as it was. The problem is that I only have one of my own (I don't own the copyright for the others) and it isn't very good, having been taken in the snows of January 1963.

 

However, to conclude this introductory, I attach photos of the first board top cut out from 6mm Far Eastern ply this weekend. blogentry-0-0-05504800-1370211352_thumb.jpgThe templates were only stuck on temporarily to determine the shape of the board and will be soaked off shortly. Using the templates to map out the shape of the board is better, I find, that relying on the background shapes that you can add to Templot. (btw I don't have any commercial connection to 85A!)blogentry-0-0-97762700-1370211378_thumb.jpg

 

Wiring? Not on 75A. It is being built not only as my own layout but also to demonstrate Acc+Ess Protocab in action. Visitors will be able to control locos from their own handsets at exhibitions so we hopefully won't be short of 'demonstrators'! Referring to my photo and the plot, the viewing position will be from the curved edge on the south west side of the plan. This is actually a very high roadway (Howard Place) from where the photo was taken looking down on the site. Brighton station was constructed on a shelf cut into the chalk hill and there is a sheer cliff face between the road and the railway. in 4mm this is around 350mm at its highest point so dictates the layout datum height for reasonable viewing. On the other hand, I might omit the cliff altogether! Viewing from the other (i.e. north east) side is less attractive as I plan to build the main line at some time in the future.

 

You can see from the plan that the whole site as modelled is not that huge, and two fiddle yards (one disappearing under a bridge to the left of the layout and the other disappearing under the station canopy ) the overall length is around 30 feet and 6 feet at maximum width. Hopefully this will be an Exhibition Manager's delight to fill that awkward corner!

 

When will it be finished, ready for display? There are very few buildings, except for the engine shed itself and the iconic water tower and three softening tanks that seem to appear in every photo ever taken of 75A! With no wiring and thus no need to insulate any of the points and crossings, a lot of time will be saved compared to my experiences with dc and DCC. There is a considerable quantity of track and some fiendish pointwork (scissors, 3 ways and several irregular slips). I'm planning to be ready to lay the underlay at around the time we have the induction charging mats ready for Acc+Ess Protocab, so that these will be incorporated in the layout, preferably within the underlay itself.

 

I'll keep the forum updated on progress and welcome any comments, criticisms and suggestions!

Looking very good, Is this 00 or 0?

 

I wish you all the best with your build. Keep us updated with the progress. :D

Acc +Ess sounds cool, could you use it with a dcc or dc layout as well?

 

Regards,

Hi Owen.. many thanks for your good wishes. Whenever one embarks on a new layout, be ready for the long haul! The layout is P4, the loco fleet so far numbering 3 locos, with another 17 kits sitting on the shelf!

I should declare my commercial interest in Acc+Ess as its founder, but 75A is very much my sons' and my own personal hobby. Yes, Acc+Ess Protocab fitted locos can work on dc or DCC but have to be controlled from an Acc+Ess Protocab controller for the moment.

 

Today's progress on the layout is to realise that I hadn't had enough time with Chris to find out from him his baseboard building plan, so I have cut out the two side inner members for the first board (the buffer stop end of East sidings). I shall cut the inner members of the ends next and then the outer members of all four sides before laminating them and joining them together.

I am very intrigued to see someone attempting anything Brightoian, as my great, great grandfather was a signal man at Brighton for most of his life.

I found 6mm ply is too thin for a baseboard top  unless you aim to cross brace every 4 inches or so.

Base boards can be made to fit together by tacking on one extra end frame to one end and setting the other back, kind of male and female. It's easy to do, makes for simple assembly of layouts at exhibitions and does away with the need for alignment  fixings.

Now THAT's an interesting thought, Shaun... will experiment. Regarding 6mm being too thin, I queried this with Chris at Wakefield but he showed me that the Barrow Road boards not being too big in width and length don't deflect the 6mm top to any extent. However, the sceptic in me says that my long and thin boards may need a thicker top so I haven't been too worried about sacrificing the first efforts (see later blog entries), as I can use them to strengthen the tops if need be.

When was your granddad at Brighton? I worked there from 1969 - 72 and visited the signalbox often. It was quite a hairy walking route, off the end of #4 platform across D,E and F sections and alongside Montpelier sidings. I always thought that the footbridge to the box was going to collapse at any time but it never did!

Thanks for your comments

Regards

The last layout sagged but lucky I'm a cabinet maker and can over come this problem.

My gt.gt.grandfather's sir name was Law I believe, that would have been my grans grandfather on her fathers side. Definately Southern days but I've no idea which box.

Might have been found trainspotting in the yard entrance near the top of Lovers walk myself in the late seventies.  

We've a Brighton here in Oregon, it's so small you could fit it under Brighton station roof!! 

 

Regards Shaun.
