I use these "Ore Cars" on the IPP&W. The Piko ones are made from the old Model Die Casting ones (MDS) I consider them not as good a reproduction as the LGB Ore Cars. Lionel used to produce an ore car too. It was better than the MDC car, but sat too high on its trucks. USTrains are using the old Lionel moulds to produce their ore cars now. Both the MDC, and the USTrains/Lionel cars have rather bad trucks, as far as durability is concerned.
Over all the LGB Ore Cars are the best reproduction of a North American Ore Car. Their trucks, although not a perfect copy of the proper trucks for the car, are very durable.
In real life, the ore cars outer wheel set are very close to the ajoining car's wheelset. To get this effect, you have to change the couplers, or go for a drawbar of the proper length. The cars were often joined up in quads, with drawbars. I think LGB provided draw bars in its sets of 4 cars.
In operation on the IPP&W we run Ore Trains. we require two sets. A set of empties, and a set of loads. The operation starts with the loaded ore cars being picked up on the run from one end of the line to the other, and on the return trip the empties are used.

BTW...the MDC/Piko ore cars are in fact 1:32 scale, while the LGB ones are close to 1:29....for those that care. The Lionel/USTrains cars are probably around 1:29.
To make the cars look closer to the prototype, we convert them to body mounted Kadee #1 scale couplers (820's or 1906's) This gets them close coupled as they should be.
I just now managed to get another 15 of the LGB ore cars. I will be masking over the data lettering, and spraying over the lettering they came with, then using a Brother label maker, reletter them with their individual reporting marks, number, Since the cars I managed to purchase are all the "Penncy" lettered ones; I just give a quick spray from a red oxide primer rattle can. After drying, I remove the masking, and the cars look like old second hand cars that have been inexpensively relettered for the IPP&W....
If you are not modelling a North American style railroad; I guess you guys would know best how to alter them to look European in style.
If I could find more of the LGB cars; I'd gladly get rid of the Lionel, and MDC cars......I consider them as very poor models of anything...but that's just me....others will enjoy their own opinion, and rightly so. LGB is not producing them at present, as far as I know.
