Help understanding a circuit.

My 2nd post since discovering the site a couple years ago.

Can someone help me understand what this circuit does?  I think it's called an RC circuit.  But what I want to know is what purpose does it serve.

What is it in? That looks like a filter of some sort.

Are you sure the bluish green components are not inductors, rather than resistors? Compare the value read using a multemeter, with the one obtained by reading the colour code.

I am not sure at all whether it's a resistor or inductor.  I don't know how to test for the difference, but I'll read up on it and try to test this evening. Here's a closer picture if that helps.

This is for a German made slot car track.  It's fed by a 14 volt .5 amp DC power supply.  The circuit pictured is connected to the positive and negative wires.
