This is what you want for a kid this age. They are battery-powered and run on the same wood tracks as other Brio trains so the locomotive can be hooked to other cars. Very fun!

+1 and make sure you set it up around the tree! How cute.

If the grandparents want to get a big gift, Duplos are great. If he's ready for lego, a lego set of any kind is never a problem since they can be used in many ways to enhance his future "trainscape". A train that runs through a land with dinosaurs? Why not?

How long do kids play with Brio? When are they usually outgrown? That's part of why I'm asking here.

I am torn between getting that for his stocking, or telling his grandparents, who usually get one big gift, to get a lego set.

PP here. A 4 yo definitely cannot handle the Lego train sets. Actually, even at 5-6 our kid (who is a serious train enthusiast) found them more frustrating than enjoyable. The Brio engine with the power is maybe $20, vs having to invest not only in the Lego set but also enough track to make it really interesting (vs just running around in a circle).
