Duplo train compatible with tracks

Lego Duplo train with engine and passenger car from set number 10507, "My First Train Set," and additional cargo car. These are the train wheel bases that are compatible with Duplo train tracks. The engine wheel base has a button and space for batteries, but we never used it with batteries so I don't know if it works. Unique light blue pieces and cute train motif on the red pieces. Total of 12 pieces that can rebuilt different ways, or great additional to a Duplo railway collection. GUC; some pieces have minor surface scratches from regular play. ** I have a lot of Duplo sets available right now and always offer bundle discounts! These pieces are fairly heavy, so can't be bundled with other large/heavy sets. **
