I am heading into the siding to meet train NHS (New Orleans to Houston, Southern connection). The name of the red over lunar signal aspect is "Low Signal". It tells me I am diverging onto another track, and that track is not governed by signals. I could well find a caboose or cut of cars just past the clearance point. The signal circuit is connected to a derail, which the brakeman on the left (Robert Hollins) has removed so that I can enter the siding at Elizabeth, just west of Beaumont, TX.
