I am really upset about the poor design of the power wipers on the drivers of the USRA Light Pacific (Item No. 52801). They are mounted so that they extend BELOW the railhead height. They may work fine on Bachmann EZ Track, but they did not survive their first and only partial trip around my layout. I use Shinohara code 70 HO, HOn3, and dual gauge track. The wipers were destroyed when they snagged on the tight clearances of my dual gauge track switches. Now I have yet-another Botchmann Display Queen -- pretty but unusable. It will sit right next to the two H-16-44's I bought years ago that SCREECH as they roll down the track on bearings that were shot after 1/2 hour of running (for some reason their bearings will not hold lubricant, though I have been told that STP oil additive might cling to the strange alloy used for the bearings).
