I had to do it. I had a loop set up for a starter set and the Brute was just starring at me from the bookcase.
It did not fit on the track.
I snapped a photo showing it in comparison to a #8 and a 339 car. Not sure if that is the smallest car made in Standard Gauge. There is stuff from the modern era that would fit inside the #8. Thinking of that whimsical freight train that Jim Kelley-Evans has.
