The brake cylinder gauge for the new CSX C40-8W on the HUD never goes to 0.0psi. Instead, it stays at 0.4-0.6psi when all brakes are released. The loco is still rolling fine on grades so it seems to be a visual bug only but with pressure this low I can‘t know for sure. The locos on Oakville have the same problem; maybe this is a core issue that slipped in at some point?
