Does anyone know what these timber plank sections between the rails are for on the old Carrizo Gorge Railway in Southern California? They appeared every so often, often near tunnels, but not consistently. Some looked almost improvised or wedged into place. Were they derailment-control devices, maintenance walkways, drainage-related, or something else?
Each one of them always had those perpendicular ties as well like you can see on the left-hand side.
