I'm hoping someone can point me to some photos of smalltime tankcar unloading. I'm working on a scene where I envision a tankcar of fuel oil is spotted and used to fuel a diesel switcher in a small but busy yard serving an industrial area and interchange. I started building a cinderblock structure to house a pump and it wasn't till I placed some of the elements that I noticed the tank car appears to be unloaded from the top, not the bottom, is that correct? I could really use some proto photos if anyone can point me in the right direction. I've attached a photo of progress so far. Thanks!
