Woodsworks posted:Hi Jonathan, 1:1 is a heck of a lot harder to put back on the rails when you fail to set the turnout correctly!
I think the detail on the Proto:48 stuff is driven by the much smaller market - with no mass-produced, injection-moulded trucks it is hand-assembled from brass castings, which lends itself to including more detail. I gave P48 serious consideration, only decided against it because I have too much invested in Ow5 already, plus I have a few 1:34 scale models of NZ equipment that I like to run occasionally, for which 1.25" IS near-as-dammit correct.
I have produced P48 and Ow5 versions of a brass truck for a US retailer, and the P48 version was so simple to make, just copy the drawings exactly, whereas the Ow5 version was a pain in the butt, worrying about clearances, having to decide what detail to sacrifice in order to fit the over-width wheels etc.

Paul,
That was what surprised me so much about the P48 truck I have. It is an injection molded truck. I have no idea on the manufacturer. Again I only discovered it was P48 and dropped between the rails of my OW5 track. Love the more scale like flanges, thinner wheels down to the detail on the inside of the wheels. It is even molded in rust brown.
However, like you I'm overly invested in OW5. More of a dream than a realistic ambition at this point.
Never thought about derailing on my 1:1 layout. 
My 0-5-0 switcher would be a little small to fix that one.
