Here is a modified sloped back coal tender I made years ago and just found it on the train shelves. Seems Lionelville coal tenders are always full of coal. This one is empty and the switcher was heading for the coal tower when the tender derailed. I just cut out the coal load added walls and a floor. Being empty will make it easier to put the lead trucks back on the tracks!
I love coal tenders. I picked up a box of 30 or so junked coal tenders years ago so hacking up one is no big deal.
