Cover art for Five Steps lyrics by Davenports, The

So as to the meaning of the song, username tcthomas4 has it exactly correct , The Five steps refers to the Five stages of Grief. The only thing I would add to Thomas’s description is the last line about Get back, the trains a coming down the track - refers to the train as the needle and the track obviously as the mark it leaves after getting high.
