Today I went to my local Talize (a thrift shop that is common in Southern-Ontario) and found in a toy bag, a COMPLETE G4 friendship express train set! it came with all the track pieces, the train and the little end caboose for critters. It also works perfectly fine too! might need a battery-change later on, but it completely caught me off-guard to find that here.
I only paid 4.99 for it too!
