It's a lovely looking prototype. Sadly my assumption about it is for the Revolution redeisgn, the designers must have made a mould precisely matching the source images of Thomas they were given, then had to proportion back some things and work round the limitations of the motor and functions so then we got what we see on the toy shelf.
