The Challenge (1998)

S3E13 Trust Thomas

James is grumbling about his task of delivering trucks to the quarry. Gordon suggests he feign an illness to avoid the chore. Just then, Thomas arrives and volunteers to take on the delivery, leading the two larger engines to secretly agree to let him do the work. However, Thomas is unaware of the impending trouble lurking further down the track, a predicament that wouldn't have arisen if not for Gordon and James's scheming.
