Though I see where the mindset comes from, since you don't see the actual steel structure of the truck, they look weak, I used to think this myself, before realizing this stuff. The BUDD Pioneer trucks have a pretty good looking I-beam of a good gauge metal which I have seen on each side. Though the metal is not as thick as I would assume it should be, it has lasted this long. And the NJT commet trucks seem to have the same design. Despite this, the inboard trucks still have a "weak look" to them, in my eyes.

But all trucks can have failures. I read that the SEPTA M-4s have had truck failures(causing derailments), but there have been instances of outboard truck failures, like on R44s, though I don't know of any derailments due to this. A miracle, mayvbe? Also, the market frankford has smooth tracks, so a truck cracking on those tracks would be caused by a low quality truck.

But thay can have an excuse on NYCTA. There are some places where you literally "hit" switches, and curves, with a very rough thrash. Plus, there is that occasional side to side banging, and even smooth curves can get bumpy. The way those cars(especially R32s) are tossed around by the tracks, their survival is a testament to the high quality construction. And for that reason, I say those cars should be used in trailer parks as homes, or something, maybe in hurrican hit areas. Think about it: they survive all that crazy stuff, there is no doubt they can survive hurricanes, and floods. The way houses are built, they snap like twigs. And I am sure an R32 can survive even a tree falling on top of it, with just a dent. Look at how they are stacked on top of each other during shipment to the reefs. Like containers. Though I know containers are used as houses(as you posted a while ago), but those probably rust. and I don't know their life span.
