Those look like a couple of foals to me, the long legs in proportion to the skinny body, mainly. Baby horses look like that. And the overall short stature makes them baby ponies, not baby horses.

So those look like two pony foals that, in addition to having been trained during their first months of life to wear a halter and walk quietly next to a human, have also been trained to wear a miniature harness and pose for a photo op. While they can undoubtedly walk ahead with the cart following them, I'd seriously question whether they're capable of responding to cues from the driver. In earlier eras, "broke" sometimes meant only "Will accept bridle, harness, etc, without panicking and instantly attempting to kick them to pieces", not necessarily, "Understands how to pull a vehicle and respond to verbal and physical cues from the driver". Out in the Wild West, a mustang was considered to be "broke" once it got to the point where it gave up trying to buck off the man on its back, but it wasn't necessarily trained to do anything for, or with, a rider.
