I recently purchased the four pack of new haven gondolas and did not really look at the pictured item( my fault), and when they arrived I put them on the track and noticed that the orange NH is inverted (HN) on the side of the car. I also found that none of the couplers will lock, The problem seems to be that the bar that the thumb tack and pin are attached to is bent the wrong way so that the pin cannot engage the knuckle. I have e-mailed menards to see if they can be exchange will see what happens.
I will say that I already have 8 Menards gondolas and more than 50 other various pcs. of Menards rolling stock and a few buildings and I have never had a problem with any of the cars that minor tweaking has not solved. For the price these are great pcs and their buildings are really nice.
