Maybe there's something wrong with mine, but I have nothing to compare it to and Learning Curve have not responded to my query, it would be helpful if the description told you what to expect from the toy. It delivers a little, each train that passes through says "rock quarry" and it makes a crushing noise when you turn the handle, other than that I wouldn't say it has lights and 24 sounds. I am a little disappointed although my 2 yr old son has no complaints. It would be better if the barrier meant that the hopper car then stopped under the chute.
I have tried the repair shed and it seems much more fun.
