Train sets, boys (and sometimes girls) and Christmas. It’s a tradition and it’s not too late. Panicked parents can still order toys online and select shipping options that should bring the bounty in on time. And prices are getting better. This one-stop train set — table, tracks and town — is $149 at Amazon and with free shipping it is estimated to arrive Dec. 22. It isn’t Brio or Thomas Tank, but then will your 3-year-old really care? If you think the little master must have the top brands (and we pity you when he’s 14 and needs a video iPod), Amazon also carries the Thomas Tank line and its many, many accoutrements, like the Thomas play tent shown above. Come to think of it, those Thomas train engines are pretty cute with their quaint faces and their alternately perky and grumpy personalities.
