I have found Menards to be a good choice if you want to buy a whole train and have a few bucks left in your pocket. They are inexpensive and there is a reason for that. While some folks have reported zero problems with them, I have found that I generally have to do some fiddling to get them to run well on my Gargraves layout. By the way, some recent RMT and Williams cars appear to be exactly the same (except for the railroad/colors and the price).
I have found that Menards has always made good on their products. While there may be problems with some cars, they have good customer support. I was interested to hear that they now require a return. In the past, they replaced faulty cars for me without requiring a return of the bad car.
Here are some of the problems I encountered and what I did to fix them.
These cars seem to be produced with the gauge (distance between wheel flanges) anywhere between 26.0 mm and 26.5 mm. I have found that 27 mm is the minimum for good tracking through Gargraves switches. MTH and Lionel have a pretty consistent 27mm gauge. I generally shot for 27.5 when I adjust the gauge.
Hopper paint is sometimes thin where you don’t see it (inside the hopper, above the trucks and on the underside), but it looks fine where it counts (on the four sides).
There is a design flaw in that the hopper trucks hit the bottom steps (the step that is part of the plastic truck subframe). The rivets on a few trucks are tight and some are not so tight. Seems like the tighter the rivet, the more the truck hits the step. This can be fixed by CAREFULLY bending the step outward. I wasn’t careful enough on one step and I broke it.
Some hoppers had the plastic truck sub frame tab on the wrong side of the car frame…easily fixed.
Some hoppers had missing a screw from a truck side. Some had the threads stripped. Some had the tiny Phillips screw head sheared off or the head rounded. I asked for new trucks, but I don’t think Menards has parts. They replaced the cars with bad truck threads. I also fixed some with crazy glue. I have not seen this issue lately so it looks like they fixed the production issue.
On some cars the coupler won’t close. The truck needs to be disassembled and reassembled with the tab on the correct side.
I add 2 ounces of weight inside the hoppers.
I’m not crazy about the silvery wheels so I apply two coats of Noelube 2 to turn the shiny wheels black.
Some box cars have the wobbles. That can be fixed on box cars by replacing the washer with a different size or by adding a shim.
On some box cars the brake cylinder/valve is too low and may contact switch points and, in some cases, getting snagged on them. The brake cylinder is rivetted to a tab on the sheet metal under carriage. The tab is bent 90 degrees from the vertical stiffener and in some cases, the tab is not bent enough so the cylinder hangs a bit lower. I tried bending the tab on one car with some pliers, but that didn’t help too much. So, I filed the brake valve so that it clears.
I’m not crazy about the short flat cars with plastic trucks, but I have several of the 14” flat cars that run well after I adjusted the gauge.
I’ll close by saying that I’m quite sure that Menards is paying attention to this thread. Most of the problems I listed above have been fixed on recent Menards purchases.
