The station areas of the line are all built as free standing brick walls, infilled with rubble and topped with aerated cement blocks, photo's showing their contruction can be found on the individual station pages.
Around the rest of the garden the track is generally higher than the ground level. I've supported the track on a metal framework topped with recycled plastic planks.
The basic outline of construction involves sinking steel posts about a foot into the ground and back filling the hole with concrete. Drilled steel angle is then used to span the gap from post to post, finally the framework is topped off with 18mm thick, 200mm wide recycled plastic plank.
The recycled plastic is a fantastic material to work with, it cuts with wood tools (I use an electric jig saw) and takes self-tapping screws. The only downside is the price and that it's only available in bulk in 3 metre lengths.
The engineering bricks I top the station walls with resist drilling for fixings so the steel angle is fixed to the course below.
Ground rises between Walberswick and Blythburgh as the line rounds an ash tree, on this section the track is laid on aerated cement blcks laid on a mortar base set just below grass height.
