Nice looking coil car Brian. I have a few of those that I bought as some-assembly-required (Red Caboose calls it RTR Ha!) I also tried a kit coil car and could not get the walkway to fit. I found that snapping it into 4 or 5 pieces got it to fit right, but then I couldn't get it glued back together.
So, that particular car is either meant to be unloaded by fellows with
very long legs or by crane. (I've also found that one of my turnouts doesn't want to snap open all the way anymore, causing about 15 cars to derail and topple over. I suppose that counts as another method of unloading cars!
