JHZ, very well done. Blends in fairly nicely. Like you said some of the finer details, ladders, grab-irons and such may be a bit too big. I could definitely see 4-5 cars and a caboose being pulled by quite a few different O-gauge locos. I don't know if I have the LEGO chops to create something like that on my own. It took me about as long to come up with my boxlike transformer as it took you to design and build the hopper.
Ed what a great way to get the grandkids involved. He did a great job.
