I knew I'd learn a few things the hard way and lesson one is make sure any essential electrics issues are sorted before pinning the track down!
Fortunately I'd only done the two sets of points before I realised I hadn't used isolating fishplates when I should have... I managed to lift one set of points without issue and corrected the error, but then it occurred to me that I still need to drill the holes for the power feed joiners and fit them before I can lay lay the stretches of flexible track. Ah well, no real damage done but a case of too much haste, not enough speed. The whole issue of getting power to the track without short circuiting everything has been an interesting learning experience in itself but fortunately almost all the work is explained in the videos I'm following online, supplemented by some Peco guide books.
Meanwhile my watery experiments continue. I'm happy with the effect that I've got with Mod Podge on my test pieces but the correct shade of paint for the water that lies beneath is still eluding me. I may try some Woodland Scenics paint, and yes, it'll be green and or brown not blue.

Finally, in the last day or so the station halt platform has received a lick of suitable dark wood coloured paint. I'll give it a wash to bring out the detail and perhaps a more weathered look. Then I'll need to paint and weather the white picket fencing at the back of the platform before committing myself with some suitable shades of Southern Railway stone and green on the platform shelter.
Planning is key though, and I need to take my time and improve my timetabling! Oh, and I feel I need to give the layout a name and given it's coastal feel I'm minded to name it 'Salterns Halt', but that's not quite 100% confirmed yet.
