Scenic contours & left handed modelling!
Well I've seen the consultant and been told that I need to have surgery to fix my damaged shoulder :-( I'm on his waiting list, hopefully it's not too length a wait! I've wanted to start forming some scenic contours for the layout for a while now, but the limited movement in my shoulder means that I can no longer reach the back of the layout with my right hand. Now I don't like having my modelling plans thwarted at the best of times, so I needed to find a way to overcome this problem! I had some polystyrene sheeting left over from insulating the workshop, so I thought this would be an ideal material to use. The main problem was that due to my limited reach, I couldn't cut the polystyrene accurately so that it fitted against the curved backscene. Fortunately I still had the full sized paper template of the layout, so I could use this to plot the required curve onto the polystyrene sheet. Once the curve had been plotted onto the sheet it was cut out using an old bread knife held in my left hand! The lightness of the polystyrene sheeting made it fairly easy to slide it into position on the layout and make any adjustments that were needed.
First pieces of polystyrene sheet in position
Once happy with the way the section of polystyrene sheet fitted onto the layout, I needed to shape the top surface using a Surform and sandpaper. This was done by removing each section of polystyrene from the layout and putting on my workbench where it was more easily accessible. Once I was happy with the shape and contour of the piece, it was glued into position on the baseboard using PVA adhesive.
Shaped and glued front section
Further layers of sheeting were used at the back of the layout to form the embankment and the lane that runs over the brick overbridge.
Additional layers of polystyrene sheet
Once I'd finished the basic ground contour, I decided to make a start on the platform. Eventually it will be faced with representations of brickwork and paving slabs, but at this stage just the general shape and size needed finalising. I decided to use foam board to form the vertical walls, following the curve dictated by the position of the inside rail of the trackwork. Strips of foam board were cut and then glued, using PVA into position onto the layout.
Platform vertical wall
Once the glue had set, more foam board was used to form the platform tops. These were cut to size using the vertical walls as a guide and then glued into position on top of the foam core and the vertical platform edging.
Platform tops
I then built the ramps at either end of the platform using offcuts of foam board and filled any gaps in the polystyrene with some flexible filler.
Platform ramps and addition of filler
I wanted to seal the surface of the polystyrene sheet to increase its strength and decided to use some flexible, crack filling ceiling paint. This was a rather stark brilliant white, so I added a pot of Burnt Umber acrylic paint into the can which resulted in a warm brown colour. I used a one inch brush to work this mixture into the polystyrene and to form an even coating over it's surface. Hopefully this will give me a strong base layer on top of which I can apply the scenic dressing.

Well that's the progress to date! I'm planing on tackling the point rodding and completing the signalling as my next project, but its obviously all dependant upon when my shoulder gets sorted.
Until the next time!
Best wishes
