I have modeled The Coaling tower, with a change as my layout trackage was already preset. These models are 0 scale. My railroad is 0n30. I have Diecast/brass engines models for the K27 (454,455,463), K28,(473,476, 475, 477) K36 (480), K37(497) and C19 (340,344).
The Oil Rack was pared down to a three car service rack.
