Due to pressure of work and other aspects of life, the trackbed for my garden line has progressed no further than the last picture. Also I needed to figure out how the line would cross the footpath to the rhs of that picture as the line needs to swing to the right, crossing the path and curving around the pond to the reverse loop.
The path is more of a goat track through the back of the rockery and around the pond. Not intended for leisurely strolling it is more an accessway to tend the garden and of course maintain the railway (when it finally opens for business).
SWMBO has already taken a tumble into the pond once but fortunately the pond liner wasn't damaged
So a permanent bridge was asking for trouble. I need something removable but easily put in place for a running session. A timber trestle was too complex for me and not suited to constant movement. A lightweight stone lookalike viaduct made from expanded polystyrene? Not really.
The idea of Meccano popped up. I had no previous experience in this medium but the simple bolt together nature of it appealed and it is real metal !
The undeniable fact that anything made of Meccano looks like like it has been under sustained attack by a machine gun doesn't really bother me. Neither does its colourful appearance. Bridges are often brightly painted. The bits needed appear on ebay in random colours and tbh I like it that way.
What you see here is one deck section. Two others will be required plus some extra L- girder pieces to provide additional strength underneath. A couple of large ice cream tubs full of concrete set in the ground with angle iron or steel pins sticking up should provide permanent anchorage for rough wooden abutments, maybe coated in grout scribed to look vaguely like stone.
It is only just wider than this loco and the approach to the bridge will be curved so clearance will be tight.
