track cleaning car for ho scale
this is a track cleaning car I made for ho scale. it requires a motor, two Wagos, a battery pack that holds two AA batteries, two AA batteries, two trucks, and a cotton t shirt you are willing to cut up for the rag. to use it simply drench the rag in isopropyl alcohol and then put it over the spinning disk and slip the ring over both of them to secure the rag to the disk and then turn it on. unfortunately I am not able to provide links to any of the required hardware because i just used whatever I had lying around the house so you may need to modify the design in order to use whatever you can get your hands on
