Matty loves setting up his train set. Every couple of days, he'll come with his request "Mummy (or daddy) please set up the tracks and the roads and Thomas and Annie and Clarabel and Bulgy for Matty to play with please mummy" [Aside: Yes, that is his idea of a proper grammatical sentence. One wonders how his little lungs have enough breath to finish such a long convoluted sentence, but then I guess he must inherit some of his dad's genes =) ]
Then mummy the engineer gleefully figures out what huge convoluted tracks she wants to create this time and sets about building them with great gusto! It's actually quite fun and it turns out different every time. In fact, I recently went and bought some "track adaptors" so that I could make more interesting routes for the train. Not that Matty realises or cares - he just wants anything that the train can run on...
After that is all done, Matty gets to run the train on the tracks and stop them at the stations. There's also a small grey road system for the bus to go on (but if you look closely at the top picture, you'll see that he's put one of the train carriages onto the road for the bus to push up the slope -- he
always does that for some reason.. odd little boy).
So, if you have kids, you must always get them toys that you don't mind playing with yourself. Makes life a lot more fun...
