I bought this set on December 26th, 2015. I wanted this for Christmas my didn't get it. Not only this makes the 4th train in my collection but it also is my 4th cargo train. I've always enjoyed building Lego trains. Not let's begin the review of this set. Locomotive: The locomotive is influenced a lot by the yellow version from set 7939. Honestly I like this one better mainly because it's red (red is my favorite color#. I like how it doesn't have a pantograph on the roof and has handrails on the sides. These features stand out the most to me. Ore/hopper car: This is my favorite freight car with this set. It look like you would see this in the mountains or something. You can load the ore by opening on top of the freight car. To offload the ore you simply just open the hatches on the sides of the ore car. The color scheme goes really well with it. Small flatcar: This flatcar is smaller unlike the ones that came with the 60052 cargo train. It has a fixed wheel system instead of a two-wheel system. The flatcar is used to transport the helicopter. The helicopter goes really well with the flatcar. Large flatcar: Now this flatcar I like much better. I've always like the charcoal plates used as flatcars the best. Another thing is I like double-wheel system train cars. This flatcar is used to transport the backhoe. I don't have very many construction vehicles but I'm glad to have a backhoe. The backhoe has buckets on the front and back. It kind of looks like a tractor but that's okay. Crane/loading bay: The crane is used to load the ore and the helicopter. It has a bucket that functions to load the ore into the ore car. To load the helicopter onto the flatcar just simply replace the bucket with a hook on the side. The area beside the crane is used to load/offload ore. Minifigures: There are 5 minifigures that come with this set. They include 2 railroad workers, 2 construction workers #1 male and 1 female), and a welder. Unfortunately when I was finished building and assembled a track layout I noticed that PF motor was functioning properly. It would always struggle and drag the tracks. I've tried fixing this problem several times such as buying a brand new PF motor, replacing this motor with another train motor, and just taking the Power Functions out and rebuilding them. None of these methods worked unfortunately. I've tried everything I could possibly do to fix this issue but nothing has worked. It still has this problem till this day. So I've decided to take out all of the power functions and play with it without the power functions.
