Not a Choo Choo, it's looks like it is probably an old Lauren Engineering kit on there, I believe they had SS, Camaro and Lumina nose conversion kits back then.
And I would say that is definitely L.E. ground effects on there.
I was going to say possibly a Camaro clip but L.E. appears correct for the reasons pointed out above. if you look close, there is a rocker panel badge just in front of the door. you'll also notice the missing marker light up front and the door mirrors and the oddball looking headlights (which are not Camaro or Elkie), so this is a 1978-81 model.
