I am now wondering if there is a limit to the number of mip/pmp files in a track, which might be more easily reached than the actual file sizes. Detroit has very many mip/pmp files, about 131 files in total. Indy 1992 has 122 files.
On the other hand, Nashville uses only 88 texture files (could be less - I think I left in some unused mip files) and Long Beach 1996 has 62 files so far. Houston has 59 despite being fairly complex.
Also thinking about the later Papyrus games, they combine a lot of textures into fewer files - for example those Page01, Page02, Page03 mips.
EDIT: As I rebuild Detroit, I am reaching a limit at only 51 mips being used - 41 in the detroi91.3do, 2 from the sky, and only 8 from trackside objects. Are the mips in the detroi91.3do being counted more? Does it still depend on file size? I don't believe I am hitting a texture size limit though... I'm still at about 1.6 MB of textures at this point.
EDIT 2: I think I've had a breakthrough on this. When my track is at the limit, I replaced all the "wall2" with "wall0" (effectively removing one of the .mips from the detroi91.3do), and then the track loads! Then I added another object (effectively bringing in another .mip into the mix) and the track doesn't load. Then I replaced all "armco2" with "armco0" (again basically removing armco2.mip) and once again the track loads with the new object as well. Why this is happening at around 51 mips, I don't know, when it seems other tracks may have a higher number of textures.
