When tamping into a railroad bridge, start at the first bridge approach timber and work backward toward the bridge to prevent raising the track too high on the approach side, which creates an undesirable transition from high to low onto the bridge; bridge approach timbers are typically 10 feet long (compared to 8.5-foot regular ties) and require even ballast distribution under all timbers, not just the center, to maintain track stability.
