We've added a teeny tiny build video of the LEGO Creator 3-in-1 mini-set, the Emerald Express steam train.

This set is unique amongst the Creator sets in that the alternate builds actually add pieces to the train, so if you buy three of the same, you can make a steam train with a linked carriage and a cool "Rocket Engine". It is also possible to extend the steam engine into a bigger locomotive with more wheels, a bigger boiler and longer cab.
