Here's a discontinued item from the Take-Along range of Thomas and Friends, which is a Lights and Sounds Thomas.

The gimmick of this toy is that it lights up and makes sounds. The engine will make three types of sounds; chuffing, whistle blowing and hissing steam. It can make the chuffing sound when it's being pushed or pulled along, while the whistle and steam hissing is down with the button on the cab roof. The lamp on the side of Thomas lights up.

The toy doesn't come with batteries. Thomas needs 2 AG13/LR44 1.5V in order to get the sounds to work.
