New Southern Green #722 2-8-0 - What are the clips

[Richard_LnRrr]

I just bought my first Bachmann train, an HO Southern 2-8-0 Green #722 and so far really like it. Included in the box with the engine were two small clips in a clear plastic bag, but no hint as to what they are.  They are all metal with three legs or pins.  What are they used for and why do I need them?
