Lights and Sounds Thomas was a special variant of Thomas. He had a working headlamp and made a chugging noise when he was pulled. He also made the sounds of his whistle blowing or letting off steam when the button on his roof was pushed.
- His prototype depicted him with a blue buffer beam, whereas his final version gained the correct red buffer beam.
- After he was discontinued, his body was used for Talking Thomas, with several phrases added.
