Hi,
I bought a 10506 set yesterday hoping to get the newer curved tracks which fit properly, but it had 8 of the older type. I'm quite disappointed, luckily I bought it mainly for the switches.
I'm wondering how to reliably get more of the good curves? Buying on ebay seems like it will be taking chances, unless I can convince the seller to take good detail pictures of all the pieces.
regards
Bastiaan
