Good to see this stuff. My "dark age" started when they introduced 9v. I was very upset at the loss of all the advanced 12v stuff (though I was too poor to even have any 12v points - let alone signals or decouplers!), and especially disliked the single-piece 9v track as it was so anti-Lego (not to mention, the brain-dead sleeper placement on the 9v/RC curves prevents you attaching 12v conductors to it!).
I could never understand why Lego wouldn't make their own metal track this way...it's just so obvious. Take a big moulded piece like a straight track, then split it into two identical rails and some standard bricks for sleepers. The moulds et al. for that are a lot more cost-effective, surely, and you can then use the parts more flexibly in other kits (witness how the rails used to be used for things like crane gantries, etc.)
The Emerald Night brought me back, and I've since grudgingly accepted PF, but I want metal rails to charge the battery box (I'm also planning on having some dual electrification so my 12v stuff can run as-is). I have assembled a small amount of 9v track, but can't bring myself to buy and disassemble a fully working 9v motor for use as a pickup, nor can I find a cheap broken one. Long story short, offer a 9v pickup (or a dual 9v/12v one!) and you can complete the dream, and save some poor 9v motors being cannibalised ;)
I'll be buying a great deal of the straights for my sidings, and once points are on offer so I can have a consistent look, I'll be buying a lot more for a full layout. :)
Yay!
