Trainworx corrugated 40' trailer question..

[nickelplate759]

I acquired a couple of Trainworx undecorated 40' corrugated trailers w/side door.
There's an unexpected round hole on the front end, as seen in this picture:

There's not part in the box that looks like it goes there (the refrigeration unit goes under the floor).  Any idea what it's for?

Freezer unit... or alternate front faces.

Freezer unit... or alternate front faces.

As good a guess as any of mine  (gophers?)  - but it's gonna get filled w/putty.

There are no instructions in the box.

Yeah.. you'd think it would include the intended piece to fill that spot in.

The photo on Trainworx web page shows the hole.  https://www.train-worx.com/?product=40200-1

The opening for the side door is "milled out" at the factory, and during that process they must have also "drilled" the hole in the nose of the trailer.  Perhaps the trailers you have were from a run of trailers that were intended to have nose mounted reefer units like the one shown in the photos below. 





Edit:  You can see the part that goes into the hole if you zoom in on the photo of the reefer unit in the link shown above.

@cfritschle Yeah, must be for nose-mounted refrigeration unit, thanks.

But the kit (same one as in the link you showed) comes with a floor-mounted refrigerator unit, not a nose unit, and fuel tank.  Which is exactly what I want, so I'm happy.
