LEGO Duplo 42121 My First Train Set Fun block play for ages 2-5 Runs on 3 AA batteries Tested and working Easy to play with, even around one year old, when they start to be interested in things that move, you can push it by hand or press the switch. You can create a lot of different play scenarios by combining it with other LEGO and Duplo series sets. Everything in the pictures is included. I think it is clean for a used item, but there are small scratches and stickers attached.
