I don't know whether to put this here, or in N scale, but it is a new product, so here goes.
Railsmith has announced models of the MILW's "Plan 4192" Duplex Sleepers. There were only two of these, and he's making them as a two-car set, in UP Yellow. Both the Zumbro River & Minnesota River were also used in UP "City" trains, so UP modelers might be interested as well.
