What situations call for an electric collar in training? Who should use these collars?

Question by KS: What situations call for an electric collar in training? Who should use these collars?
I’ve never had any experience with electric collars, so just asking the dog community what they know.

In what training situations should they be used?
Should only experienced trainers use them or should average pet owners be taught how they work/how to use them as well?
If you have used one…what issue were you addressing? Why did you choose an electric collar? And what were the results?

What would you call the bottom 2 pieces that go underneath a ho scale train car?

Question by mandylover: What would you call the bottom 2 pieces that go underneath a ho scale train car?
I know the train cars have wheels, but you have 1 piece that carries 2 plastic wheels (on the left side let’s say), and there is another piece (on the right side let’s say) with another 2 wheels? What are those things that carry the wheels called? Mine I have on trains are plastic. I want parts, and I don’t know what to call them.
