For a second, I thought you meant your third railway photo showing a switch ;-) BTW - where's the one going green? I know there are plenty of funky ties out there, and not just in someone's garden. I don't know about other places around the world, but some low-budget American logging lines just laid rail on cut tree trunks,

and others - called "pole roads", ran engines and cars with wide, dual-flanged wheels on log "rails".

I took "the switch" to be some sort of junction box, but it's also a part of what made me dubious. I can't recall if I saw any sellers calling it a harbor lamp or not, but I couldn't help but think of pier pilings when I saw this - I suppose also because the rope lashing looks so nautical.
I have written to MIG asking if there is a prototype, and requested a photo if they have one. We'll see - if they send me one, I'll post it here and admit I was wrong.
I've done all the Google Image searches that I care to. If anyone has books or photo stashes they want to look through, go for it.
