12pcs Model Train Bogie 1:160 N Scale 33" Plastic Wheels Model Railway Accessories (N Scale)

Good quality

1) The wheel guage is extremely narrow resulting in picked switches and crawling over the rail when pushed.2) When replacing stock trucks, there isn't enough material in the bolster to completely fill the space between the truck pin cap and the body. This and the bolster hole being to small leads to truck slop of as much as 0.25 Inches.3) The couplers are difficult to mate with any other couple other than one of their own type. They will NOT mate with a "scale size" N scale coupler at all.I've purchased two of these sets (2nd purchased before I really evaluated the first set!). I would NOT have purchased the 2nd set if I had discovered this earlier. I'll be returning these shortly!

I haven't really tested to see how well they track on the rails. They have plastic wheels and I'm not a huge fan of plastic wheels. (I'm moving from HO scale to N scale so not sure if the smaller scale makes a difference on that detail) I knew it was plastic wheels before i purchased i figured I could probably find a good source for metal wheels later if I'm not happy.Install was easy on my old rolling stock with push pin for holding the trucks on. Which is 90% of my rolling stock.Screws provided are completely useless. Need 1 size bigger and to be about 1mm longer to go through into the truck frame with enough bite into the car frame to hold. Might work if the car has a peg built in to the car body with a screw. But then you could use the old screw.The washers ended up being the perfect size. I was able to put the peg through the washer and use the old peg to hold the new trucks on. Instead of the provided screw. the hole on the new trucks are to big and the peg goes right through if perfectly centered in the hole on the truck. But with the washer it works. (To big is better than to small)I will be buying more for the rest of my Rolling stock.

nice little plastic snap cases to not lose the tiny parts.easy to install to repair the train cars.

These are nice looking trucks with good knuckle couplers. However, the hole in the truck for the bolster pin (to attach the truck to the car) is very large. Most pins that come with cars will not work. The trucks are supplied with tiny screws with heads that are too small to secure the truck, so washers are supplied, except when a washer is used, the screw is too short to secure the truck to the car in all the cases I've tried. So, while these are a great value, keep in mind that some fiddling and other parts may be needed.

I needed these to finish out a final layout. I'm very pleased.

work great with n scale trains

They roll really rough. Don't buy these, I will be returning them. I would rate these as no stars.
