I'd like to buy my son a Lego train set for Christmas. He loves trains and has a wooden set (Brio with Thomas the Tank Engine engines) but he's now ready for something a little more complicated and I thought of lego, his other obsession!
I'm not sure what would be best- I'm worried that he might be too young for the things I'm considering http://www.amazon.co.uk/LEGO-7938-Lego-Passenger-Train/dp/B003A2JCQ8/ref=sr_1_1?ie=UTF8&qid=1291053546&sr=8-1 but simpler stuff seems a bit pointless as it's not so different from what he already has. I'm obviously happy to help make everything but would be keen for him to be able to play with it fairly independently once made.
Do you think a conscientious 5yo could get to grips with a set like this? If not, what would be better?
Thanks in advance for any help.
