Bluebird Toys

In 1997, Bluebell Toys released an incredibly compact but action-packed playset featuring Thomas, Percy and Bulstrode. The engines and rolling stock had metal rivet wheels that allowed them to run on three-dimensional yellow plastic rails. Features included a tunnel, station and the ability to transfer loads from a truck into Bulstrode. Smaller sets featuring other characters such as James appeared later. They could fold up and be carried to other locations. The Trains are about 1.5cm long. A magnetic set was even offered later that allowed you to control the trains.
