Police are hunting burglars who stole a 30ft-long land train with a Thomas the Tank Engine face.
The distinctive attraction, which has an orange canopy and two passenger carriages, was taken from a shipping container which was broken into at the seafront in Lowestoft, Suffolk Police said.
One Twitter user wrote: "What will the thieves do with it? Repaint it and try their luck in Clacton?"
Police said it is thought a lorry may have been used to remove the vehicle.
The incident off Kirkley Cliff Road, between Kensington Gardens and St Mary's Catholic Primary School, happened between 4.30pm on Tuesday and 10.45am on Wednesday.
Anybody who witnessed what happened or has information about where the land train is are asked to call Lowestoft police on 101.
