You are sort of correct in this interpretation. The two links are not solid. The one between the two cross shafts is linked via the compensation levers presumably to cater for expansion/contraction of the links due to temperature changes. You can see this in my black and white photo and Dave's drawing in the Carriage Brake thread. From memory the drawing you mention shows this compensating arrangement. The levers also reverse the direction of push/pull between the two cross-shafts, so a direct link between the two would not work (one end would apply the brakes, the other release them).gdb wrote: Agreed... My interpretation of photos is that the handbreak linkage from the break column connects to the nearest break cross-shaft before reaching the battery boxes. I have (a part of) a drawing of an angle-iron underframe and that drawing appears to show a break rod which runs from break cross-shaft to break cross-shaft, between the battery boxes, so that applying the handbreak in the guard's area results in the break being applied to each bogie.
