LEGO Creator 3 in 1 Emerald Express Train (56pcs) Figures Building Block Toys

I review many of the Lego train sets and wanted to make sure that people understood exactly what 31015 is. This is a very small, sub-mini-figure set, that has an MSRP of 4.99. It was introduced late 2013/early 2014. It is always wise to crosscheck with Lego on price and availability.This train is not compatible with Lego's regular trains. Set 31015 is not meant to run on any track. The set only builds one engine or car at a time, so if you actually want a full train, you will want to purchase a few of these (they can be connected together). There are three included designs: a steam engine, a carriage, and an aero-styled engine.That being said, this is a fun little set. The three different designs encourage kids to build and rebuild. As a Creator set, it uses only general purpose bricks rather than specialized, one-use bricks. This makes for a very useful collection, albeit a small one.
