The Roco Rh 310 in HO scale.
When it was released, the bar for high volume models was significantly raised. RP25 wheelsets, smoke box doors that open, DCC installed, and incredible detail.
Imho, this model really made an impact when it was released - more Roco Platinum models followed, and other manufacturers adapted to the 310s standards as well.
