This kit took quite some time to finish. There are many parts and some parts don't fit quite right. You will need to do some filing and filling to get it all to look right. I added extra details like platforms, stairways, etc. to more fully represent an actual coke facility. It would look perfectly fine without these details but the customer I built this kit for wanted all the extra added details. I had to raise the coal bunker to make it clear the Larry Car. I also added the catenary lines for the electric pickup on the Larry Car. I added details to the interior of the operator's cab, as well. Both the Quench Car and the Larry Car were both pretty straightforward builds with good fits, etc. All-in-all, it took some time to finish the entire kit but the final outcome is worth the time if you don't rush things.
