I just received my order of Menard's Reading hoppers, eighteen of them. Initial impression when unpacking them is very good. The graphics are very sharp and colorful, good looking car. They added some graphics to the ends, a nice touch. They are a bit lighter than the boxcars, coming in at 11 oz each, I'd like to see them a few ounces heavier. Unfortunately, they seem to have secured the fake coal load in from below, it's going to take some work to figure out how to get it out of there to add weight. The couplers for the most part, worked better than my initial samples of the boxcars, only one problem coupler so far.
All good things must come to an end, and after an initial track test, the not so good things started to show up.
First off, the trucks are riveted to the truck support plate. Worse, the truck support plate is plastic, and several of them are warped in my cars, so the trucks are actually sitting cocked to one side. A number of them exhibit this issue to some degree, but I have a couple cars that are totally unusable because of this issue.
This flaw causes the cars to derail on switches and worse caused a short without a derailment that baffled me for a bit. It was on the switches 15 feet away from the lead car. The engine and lead car were right on a double switch configuration, so I wasted quite a bit of time trying to figure out why that was shorting, and couldn't see a thing wrong. It was only when I started disconnecting cars and moving parts of them that I noticed the issue was actually around the corner on another switch, that's where the problem car was parked!
Finally, there is a couple of flaws that affect some or all the cars. The step that is molded onto the truck support plate hits the truck when the trucks swivel. I managed to run them on O72 curves, but they had real problems on O36 curves as the trucks couldn't swivel freely, and the car would derail. I'm guessing the cure will have to be to lop off the steps.
The second issue is the riveting of the truck to the support plate is inconsistent, and some of them are too tight and will also cause an occasional derailment on tight curves. Again, this wasn't too much of a problem on O72 curves, but showed up on a handful of the cars on the O36 tests. I was able to loosen a couple up by working them and a drop of oil, but there are still several that are very tight and don't like tight curves.
Here's the interference with the step and the truck illustrated.
