This is one of the first two PBL Sn3 trucks I have converted for use in OO.

I will have more on this conversion later in the summer as I work out the details/bugs better but the short version is it is not that complicated and these trucks roll like crazy! Also they scale out well in OO. For these first trucks I used the original wheelsets but I will be looking at other options ASAP as they are a bit undersized and they derail easily, I believe because the tread width is narrower than NMRA standards for OO. Overall, however, very pleased and encouraged by this as a tactic to create OO trucks. Click on the photo for a closer view.

The car in the photo is Picard, the scribed body style, which I built up in the 1980s. I have three more cars of this same general type nearing completion now that will look great riding on these new Andrews trucks.

UPDATE: I now have wheelsets based on Athearn 36″ HO wheelsets on the trucks, and with future purchases I put the Sn3 wheelsets up on eBay and sold them easily. These trucks look and operate great.
