I see another minor problem with it. The model is made out of two cast parts.
I think that the best would be to cut the bottom part in two and glue them together again.
Alignment of the strengthening ribs will be noticeable. First take another photo of the side profile with the bottom view with those ribs touching and align and see where the problem is, maybe one of the two molds shrunk or expanded.

Yes, it looks like this. Either one of the molds shrunk or expanded or one of the castings shrunk or expanded.
The first picture of Ian's model shows the same problem, so i am probably not alone with it.
I don't know any better way of fixing it. If I cut it in the middle and glue together again, the ends will be aligned and the misalignment in the middle will be only half of the current one.
It is 0.5 - 0.6 mm off now.

They are all the same. The only way I could cast this was in two parts, not one as the original master was built. By the time I got back to this there were only a couple of usable castings left to re-make the master using the top half from one casting and bottom half from another casting and this resulted in the rib miss-alignment.

After having had it collect dust for so many years I just decided to live with the problem and get some cars up & running. When running the rake of 8 cars behind a motorised Lionel GP unit on my small exhibition layout most viewers are more interested in it being TT than to notice the faults in the cars.

I have thought about doing a new chassis piece but, with so many other projects "on the bench" I prefer to use what little modeling time I've had lately trying to get something else nearer to completion.

I can certainly live with the discrepancy. It's hardly noticeable unless you're inspecting closely, and as Ian says the average viewer at a show won't notice.

I don't make my models for any average viewer at a show. Do you?
I will try to fix it. It is a nice model.

I don't know why I do it sometimes, but mostly I make them for the little man inside my head who at some point tells me it's good enough.

Here are some ATSF heralds to help with the Ga-152 models.

Below is a PDF of the complete 6ft TT-scale ATSF herald for the GA-152... and an 'exploded' 3-part version, with tapered wings to allow conformance over the deep ribs of the TiTan TT model. These decals should allow the yellow-painted background to show through the clear decal film. There are tiny guide marks to allow alignment with the ribs... these should be removed before over-coating the decal.

An alternative application is to paint the rib sides black, and just trim the two rounded sides at the guide marks, fitting them flush to the rib. The "T" could remain un-trimmed, as the edges of the letter hang over the edge slightly.

Note that this artwork is 200%... so the PDF can be printed at 50% on any printer using appropriate decal paper.

What makes this a hopper and not a gondola? Is it the tapered sides and ends?

The name "Hopper" was probably chosen because it is in the old magazine of 1972. See here.

It is a high-side rotary coal gondola. Not helpful is that the ATSF has designated all gondolas, open hoppers and covered hoppers as Ga-class (or gondola cars).

Here's my finished article, with just a touch of light weathering. Not my best effort in some ways, but I did like the decals and the way the yellow lettering is not a bad match for the yellow paint job.
