Desperately slow progress, what with family commitments and other life stuff...

However, the dropped (removable) board now has its elevated sections for the bridge under the mainline and a shorter bit for the head-shunt.  Once the alignment was drawn in to fit the plan, the track board supports were glued (with screws in some cases) and various fillets added for lateral strength.  Thought I'd try some laminate flooring underlay foam on this layout - seems to stick down OK with PVA glue, but let's see how it takes paint and Copydex for the track side.  Early tests reveal it's quite quiet, so here's hoping...

Oh, and the track and points have arrived - just need to order some microswitches for the frog switching.
