International Railroad Discussion > The "B" truck of a BB40-9W (Brazil)Date: 05/17/18 17:17 The "B" truck of a BB40-9W (Brazil) Author: pedrop Hi, a close-up on the "B" truck of Vale BB40-9W 1309. I really like this kind of truck. Some model railroaders use to model it using Frateschi U20C truck shell.

I would guess that those are the air brake cylinders. I would further guess that the chains run to a hand-brake mechanism somewhere on the locomotive. Look at how the chains are attached to the lever running to the brakeshoe arms. Interesting arrangement. |
