That one in the picture is from a later run of the mill gondolas I own. If they are using the same truck and coupler design as the first run, there is a high probability of derailment on turns.
OK, thanks. It has to be the same trucks. I searched and it seems like people on here allude to the 2017 gondola trucks being a step backward but they don't come right out and say anything about running issues/derailments. I ordered two milk cars with the infamous trucks and one is fine going through O36 with cars on either side. However, the adjoining cars have articulating couplers and seem to compensate for the lack-of with the milk car. I wonder if the same would apply to the gondola since I would only be running one gon in the train?
