Custom Model Depot has released an HO scale version of the distinctive Dalman-Andrews truck used by several railroads. The trucks are solid one-piece sideframes and bolsters with brake levers and shoes, comprised of "nylon like" 3D-printed resin. The detail, while not like a Tahoe Model Works or Kato truck, is a lot better than the Cape Line trucks of years past and is certainly acceptable, especially given the distinctive nature of the prototype. (note: I am not certain if CMD has worked out the kinks of their web site yet; I was able to manually order via email and submit a paypal payment as opposed to a more typical ecommerce checkout. I did order some vehicles, too, and will profile those in a separate, future post.)

The trucks above were fitted with Reboxx 1.020" length axle. 0.088" tread with wheelsets. I filed little notches in one of the openings on each side to ensure that the axles could be inserted before I stressed the truck castings too much (after some previous experience with 3D-printed, one-piece trucks.)

Below is a roster I assembled with the help of others of prototype uses (known to me.) While I would be surprised if it is exhaustive, it is a foundation. If you are aware of other applications, please leave a note in the comments section below and I can update the roster. I have not highlighted it in this post, but Richard Remiarz has identified distinct details and nuances among the bolsters and attachment of the journal boxes that provide further differentiation, meaning there is not a one-size-fits-all Dalman-Andrews truck.
