The East Anglian Railway Museum, near Colchester, Essex, has a beautifully restored Great Eastern Goods Shed as one of it's main buildings.

I wanted to feature a decent-sized goods shed on my layout and thought that this one would fit the available space nicely.

Here is a photo of the prototype:



At the time I visited the museum, I took lots of photographs of the Goods Shed from as many angles as I could. I also measured a single brick, together with it's share of the mortar. This turned out to be 9" x 3" which in 'OO' scale; 4mm=1ft, is 3mm x 1mm. I was therefore able to draw up reasonably accurate plans by counting the bricks on the photos.

This having been done, I made a cardboard mock-up, just to make sure it would fit onto the layout.



Here it is with a Superquick Goods Shed kit, just to give an idea of the size:



The model will be built from embossed Plastikard and because the prototype was built using English bond brickwork, some suitable stock was purchased from Slater's.

Work has now begun and the four main walls have been cut out. Each will now have layers of plastikard built up to give the relief effect evident on the prototype. I will post some photographs as work progresses.

The end of the shed furthest from the office was tackled first. This is what I am trying to achieve:



The door opening, triangular recesses and window openings were cut out from what I termed the �base layer� of embossed plastikard. There will be layers either side of this to give the required depth of relief to the brickwork.



It quickly became evident that the 15 thou thickness of the embossed plastikard wouldn�t give enough depth, so strips of 40 thou x 80 thou plain plastikard were glued edge-on around the lower window panel. The two lower windows were cut out and the panel glued behind the base layer.

I used a �Jakar� Compass Cutter, �2.75p from a local craft shop, to cut the curved tops of the windows.

Plain 040� white plastikard was used for the windowsills and the various stringer courses were added.

The 3-course arches over the top of the windows were marked out on the back of some scrap material then cut out using the Compass Cutter.

Glazing will be done towards the end of the project.

The lower window panel construction is complete and will be left to dry thoroughly before the top windows and panels are tackled.



Here is a seven-step guide to the way I made the window arches for the goods shed:

1. Mark out a circle the diameter of the top of the window with a compass cutter. Mine happened to be 14mm.



2. The prototype had three-course arches, so concentric circles were added at 18, 22 and 26mm respectively. These weren't cut so deep as the first circle.





3. Using the centre point as a guide, start to scribe lines across the circles, keeping them as even as you can by eye. Start with one line. Add a second line to make a cross, then carry on dividing each segment until you go cross-eyed!



4. You should end up with something like this:



5. Cut the circles in half, then remove the centre pieces.



6. Carefully cut away the waste outside the circles.



7. Try the arches in place on the model. They may need a little trimming with a small file to get a perfect fit. These obviously haven't been trimmed yet!



That's all there is to it. Providing your required arches are semicircular then a compass cutter will do the job. Otherwise it gets a bit more complicated! :shock:

The remaining 3 arches over the top windows and the wider one over the door have been completed. I made the one over the door by cutting three single brick courses and cementing them in place, one after the other. The arch capping strips were then glued in place. The rest of window sills and the rain strip over the door opening have also been fitted.



The first end wall is now complete except for glazing and painting.

The doors will not be made until later. I intend making all the doors as a batch. The ones at each end will be fitted in the open position so that vans can be shunted in and out. The positions of the loading bay doors have yet to be decided.

To be continued.

Perry

I thought you were pretty good before Perry but your technique and workmanship justs gets better and better. That truly is a brilliant start to what I feel sure will be the best piece of scratchbuilding we will have seen on this forum so far.
