THE BATTERY SHOULD GO IN THE BOTTOM OF THE TOY.YOU MAY NEED A REAL SMALL SCREWDRIVER TO OPEN IT.

2 options.

1.if its the kind that fits on the wooden track look for a screw (philips/star screwdriver) on the underside of Thomas near his face. The body shell should lift off.you will then see the battery.

2 If it's the plastic blue track you have to squeeze the right center wheel and left center wheel. Thomas has 6 wheels so the 2 center/middle wheels, after squeezing this will then make the top portion pop off.

My child has a similar train but it is a Thomas instead of a Percy. There is probably a screw on the bottom. My son's train has three screws and the one in the middle (+) is the one that opens the train so I can put a battery in it.

I brought one a few days ago and out of the box it talked but would not move. I returned it to the store for a replacement. I noticed that the back wheels under the on and off switch have weight on them before the train will move. If the train is not sitting on the track, it will not move, That is what makes thomas stop at the station

James the train has a tender attached to him. On top of the tender there is a black plastic piece that looks like coal. Slide the black plastic piece towards you and you will see the battery underneath it.

its defective there was a recall 4 days ago
