Sounds as if Atlas bought just full scale MTH diesels and cars, no semi-scale tooling (sorry I have not had time read these previous five pages of comments 
). Too bad, as its getting harder to find "small" cars to run on small layout sharper curves without looking out of place (trucks jutting out, car body hanging way over the curves). The few full size cars I have are parked on sidings in far corner of layout to diminish the out of proportion look. I can run those "huge" cars for myself but never when there is open house.
But that just me and my layout 
.
