A few years ago I found a link to a site called Altered States Magazine. ASM had very good Toy Fair coverage, particularly of LEGO. These days pictures from Toy Fair are pretty prevalent but ASM still has very good coverage.
Unfortunately there are no pictures of the 2010 trains. At least none that I saw in my quickl scan through. Link to ASMís Toy Fair Coverage: http://toyfair10.asmzine.com/gallery/lego/
