NifelizBig Boy Locomotive, Articulated Steam Locomotive Building Block Set, Legendary Steam Train Display Kit for Gift Giving (1,818 Pieces)

I bought this set with low expectations given the reviews. But I was very pleasantly surprised. The set is well designed and the instructions were far easier to follow than I expected. I think I had maybe one or two very minor detail pieces missing, but I used some older bricks from a different set to fill the gap. The instructions are not always easy to follow, and I had to pull things apart and rebuild more than once, but the bricks held together well and I never had an issue with the set being fragile or not holding together. It's meant to be a static set, so not made for playing with or trying to put on a a larger track. But it makes a great discussion piece and overall looks very nice. Would definitely recommend for an older kid, teenager, or lego adult that is looking for a bit of a challenge.

This particular set is a perfect example of the ridiculous price gouging from the name brand brick construction companies.This was extremely fun to build. I received it as a gift for Christmas 2024 and was immediately surprised and admittedly somewhat intimidated by it. The packaging is excellent and the instructions are clear and concise. The added bonus of four small folding boxes was a welcome addition. I advise using tape or staples to keep them together. There were no missing pieces!!! The fit of pieces was extraordinary and this made the whole process more enjoyable. Overall a great looking model considering the cost of competitors versions.The only negative I can offer is the inaccurate length of the four pieces of narrow tubing that run the length of the boiler. Normally wouldn't mind this but they are also mounting points for other pieces so I had to improvise in order to complete the build.Overall a super fun build. It took approximately 10 hours of intermittent work and I really enjoyed the process. I definitely recommend picking one of these up. Way to goNifeliz!! Great product. I hope this review helps you in your decision.

There are two versions(or more) of the big boy. This is the good one. 1800pcs. The lesser not good option is the one many resellers are pushing that is only 1608pcs.The kits are noticeably different. Stay away from the 1608pc versions. Bad kits, bad design, terrible instructions.You will be happy with the 1800* piece kit. Instructions are great! Fabulous display and all around great kit.

I've been a lifelong fan of LEGO models, but real LEGOs are so expensive that it is difficult to justify the purchases sometimes. I have tried several of the "knock-off" brands and usually there are serious deficiencies in both block quality and fit, as well as overall quality control in missing pieces and designs that just don't go together well.This is my first Nifeliz model, and I must say I am impressed! I've also always been a fan of the UP 4000 series locomotives, so when I saw this model, I had to get it. The fact that it's not as dirt cheap as other knock-off brands and the overall positive reviews gave me a little more confidence in the purchase, and I am glad I made it. Overall, it took me maybe 12 hours or so to build over the course of an evening and the following morning. It is BIG! The overall dimensions are about 31 1/5 inches long, 5 1/5 inches tall (including the track base), and about 4 inches wide. Block quality is excellent, just about as good as real LEGOs, though LEGOs are slightly more aesthetically pleasing (things like the LEGO logo on top of the studs, where these just have nothing or mold marks). The pieces are packaged in a very clear way, with each bag of parts corresponding to a specific series of steps. No having to dig through different bags looking for the right one. Each bag contains all the parts for the steps printed on the bag. I also very much like the inclusion cardboard "storage trays" that made the build far easier to manage. A few extra pieces, and no missing pieces (though I thought I was missing one tiny piece, but I found it in the next bag).I am a bit disappointed in some design choices. For example, the coupler rods (the parts that connect to the drive wheels and the steam cylinders) only connect to two of the drivers (drive wheels) on each section. The front two drivers on each section are just free spinning. Additionally, the steam cylinders on the rear driver truck basically don't exist, and the pushrod just floats in the open. I don't know why they didn't use a few cam and link parts to simulate the cylinders like they did on the front (see pictures 2 & 3).Overall, I am very happy with this build. It went together quite easily, with the exceptions noted below, and the final model is quite a site. Read on for details on the few problems I ran into.PAY SPECIAL ATTENTION TO THE INSTRUCTIONS WHEN DEALING WITH PLATES BOTH WITH AND WITHOUT HOLES! The instructions are not very clear in differentiating these parts, and it's easy to put down a bunch of plates only to find you need to break them all up and start over. The instructions are fairly good, though the choice of colors (making previous steps all the same grey color in the current step) sometimes makes it a little difficult to see what your supposed to do).Lastly, there were a couple of loose fitting parts, one of which makes the build extremely delicate to handle (which is to be expected, but it's much worse because of the loose parts). First, there are a pair of decorative bars meant to simulate the handrails around the front of the boiler. The piece in question is a pair of parts that slip onto the ends of a plastic hose/tube that simulates the rail along the side of the boiler. These two parts simply slip over this tube, and the fit is extremely loose, especially on the right side (there is no grip on the right, it simply falls off if not braced). I added a pair of extra black beam "connector pins" to the build that tightened these pieces a little, but they are still too loose (see pic 4). Also, those plastic tubes were cut slightly too short, exacerbating the loose fit problem. These tubes should have been left slightly longer and let the builder cut them to exact length during the build.The second loose fitting part is the one that makes it so difficult to handle. The Leading Truck (the four small wheels at the front of the locomotive) is built around a rather interesting set of axle (spline shaft) connections. Among these are four gray pieces butted against each other over a short spline shaft (the gray pieces underneath the blue bar in the pic). Unfortunately, these pieces are the only things connecting the front two wheels of the truck to the back ones, and they are both very loose fitting. As a result, if you pull on the nose of the locomotive any, these pieces separate and the forward part of the Leading Truck comes away. It is also extremely difficult to put these back together because all of these parts are free-moving axle pieces meant to allow the Leading Truck a good deal of movement.There are other strange design choices, such as bevel gears being installed on almost all Drivers, but they don't do anything. It's almost like the designer intended to have a gear-drive system inside to link the Drivers together but then dropped the idea. The plastic ribbed hoses on the side were also not thought out well, as the forward one is supposed to be bent, but the piece at the front of the hose only attaches to the train at one point, so it can swivel and the force of the bent hose just pushes it away. I ended up just cutting the hose shorter and connecting it to a different point on at the back. It's not right, but it's better than before.

Love trains, especially the Big Boy. This was my first brick style kit for a train. Came packaged very well. Kit was missing one small part, but did not keep me from finishing the train. Nifeliz was very responsive to email and sent missing part quickly. Luckily enough it was easily installed with out dismantle. Did not hesitate to order from them, now have 3 of their large 3000+ piece car sets. Very happy, and saved alot of money.

Definitely a fun and challenging build BUT, they need to invest in better molds. Tons of pieces do not fit together well. Either have to finagle them to work or you need to use glue to hold together. Whoever wrote the instructions must have ADHD. You don’t completely finish one section until you’re put on a side quest to put together something else. Once you put them together, everything falls apart because they don’t hold together well.Pros: fun challenging buildCons: poor mold quality, instructions take you on 50 side quests before you combine everything together.Overall: good for the price (could be a little cheaper). Grab some superglue, and get ready for things to fall apart. Better off spending the extra money and going for actual LEGO brand.
