Presumably that's what he meant. DMIR ore jennies had a seperate brake pipe/valve. It's called "straight air" or Orinoco retainer. There is a seperate handle on the engine to set up the brakes and it can be maintained as you use your normal automatic brake. The Orinoco *retainer* name hints at its intended use. It basically takes the place of a conductor going back and flipping some retaining valves to hold a set on cars.

This system still exists today with CN keeping captive AC44C6Ms in the area(3300-3350 mostly) being fitted with the straight air handle.
