I hadn't noticed the A-pillar deflectors. The one across the windshield is [apparently] translucent. It could be a sun shade for the driver.
I think the locomotive deflectors are done right, although I suspect it was for mitigating the black smoke plume. They will capture more air stagnating on the front and pressurize it.
