Great looking build
An awesome addition to my collection of builds from Nifeliz !! I have done many of their kits and will continue to buy from them. I also have many builds from Lego as well and find that Nifeliz is real close to the same quality. Overall, I only had minor difficulties with some of the smaller parts that held the railings and a couple small pieces on the front and rear bumpers staying in place. I rectified the issues with a little hot glue and called it a day. The finished piece is amazing with great attention to details. The instructions had a some glitches with details and legibility, but I just broke out the magnifying glass and all was good. Great build at a great price !!

Excellent Quality Build
This is my second Nifeliz locomotive build and I have to say that they are on par with the big name brand and the value is exponentially better. They are fun to build, the design is excellent and the final product is beautiful. This one is a little more sturdy than the Big Boy when complete. Would have liked some kind of red lettering on the side to match the design

Very nice project without the name brand pricetag!
The husband loved it. He did say some of the more intricate parts required some glue to hold them together at times. But he now has it completed and proudly displayed above his side of the bed! The pieces fit together easy - good quality and looks great!

Great Find!
Excellent train project model, although it’s not exactly the diesel train I was looking for, but it absolutely makes up for it with its size and scale. Instructions were detailed enough, with some mild confusion on my end for the placement of certain parts or the particular method as to which I was supposed to attach certain pieces. I wouldn’t call it exactly “kid-friendly” as there are a ton of small pieces and I managed to injure myself assembling it, as well as it being particularly heavy overall. Looks great on my shelf, and gives me half a mind to modify the wheelbase and attach electric motors and lights to it just to take it for a spin on some tracks. Satisfied overall, but left hoping someone replicates an Amtrak Genesis or Charger train, or at least hoping I can find an ET44AC like I was originally searching for; plastic brick trains feel much more fun than small simple replica metal trains.

Awesome display model
My 10-year-old Grandson loved putting this together. It’s the first “lego” he’s owned that will stay assembled and put proudly on display for keeps. His brother is already eyeing the tanks!!!

Good quality- would buy again.
I put this train set together with my 7-year-old, and it was a fun! It took us about 2–3 days, working in a few-hour stretches. The instructions were decent, but there were a few areas where they could be clearer—some steps required a bit of guesswork (but no more than other big box brands I suppose). That said, the final result was absolutely worth it! The build was engaging, the pieces fit well, and my son loved seeing the train come to life. Overall, I highly recommend it for anyone who enjoys detailed building projects! Totally worth the money- I will buy another set again.

A pretty good set
It's an awesome set. The size is perfect! I scored this a 3 because the instructions were very annoying. Lego shows different angles while assembling. This set did not. I had to use a magnifying glass in order to see some of the proper connecting points. I'm a huge fan of the DDA40X locomotive so everything else is awesome. The price wasn't too bad either.

Espectacular locomotora DD40ax. Gran calidad de armado. Llegó en caja. Muy bonitos detalles. Solo se batalla en el eje de los trucos, no alcanza a dar vuelta. Está genial su base para exhibición.
