On the smallest side, the tiniest critters in the italian state FS inventory- Di Horatius di Wikipedia in italiano, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=9140814 Built form the late 30s licensed by the german factory Breuer, these 70hp machines were used in light shunting for 40 years and over..... some were also used by the italian military in Africa or in Italy itaself and ended up being used by USATC. So small and light that there is provision to tranfer part of the car weight coupled on the critter to increase the tractive effort.

while most of the critters shown are prototype, these are HO models from my small layout .. Eb 002 by wvgca posted Jun 1, 2021 at 9:36 AM
The tiny critter had also been produced by rivarossi in HO scale The tiny motor is inside the cabin, hidden by the side curtains; it is also DCC ready. As you can imagine, it can pull no more than 3 or four cars and is a nightmare with regards to current pickup and slippage.
