<p class="MsoNormal">What would be interesting use of these would be in open top hopper cars with working discharge gates. Then that would make more fun to operate coal or gravel trains. These along with BLE radio chips, custom PCB, controller might fit
into O scale cars. Too big for HO, but perhaps the next generation will be even smaller – the Nano Stepper Motors.

<p class="MsoNormal">For HO, these could work in buildings – opening, closing doors as an example.</p>
