Track Speed Limiter

Track Speed Limiter reduces the speed limits and maintenance costs of existing railway tracks. Choose a speed, preview the affected section, and click to apply it. Maintenance costs are calculated from the track's original maintenance cost and maximum speed. Features - Available under Tracks → Tools. - Set a speed using the slider or manual input, from 1 to 600 km/h. The applied speed is capped by the track, bridge or tunnel limit. - Modify the hovered segment and up to 16 additional segments in each direction. Hold Shift to modify a single segment. - Selection stops at junctions, track-type changes, construction-owned tracks, or segments already matching the selected settings. - Yellow indicates a different speed; blue indicates a matching speed or selected section; red indicates a request above the available maximum. Maintenance - Maintenance rates scale with the selected speed relative to the original track maximum. - The maintenance floor is 60 km/h. Tiers use 10 km/h steps through 200, 20 km/h steps above 200 through 400, and 50 km/h steps above 400 through 600. - Speeds between tiers use the lower maintenance tier. The speed limit itself is not rounded to a tier. - Repeated edits do not compound discounts. Restoring the original maximum speed restores the original maintenance rate. - Bridge and tunnel support-structure maintenance is unchanged. Compatibility - Uses each track type's own speed limit and original maintenance cost, including modded track types. - Preserves track geometry, electrification and decorations. - Preserves Real Track Cant's train-tilt markers. - Load after mods that provide track types. Notes - Applies to standalone railway tracks. Station, depot, industry and other construction-owned tracks are excluded. - Keep this mod enabled when loading saves containing its maintenance variants. Those tracks reference resources supplied by this mod. - Test the mod on a separate save before using it in your main game. - Report errors in the comments and attach stdout.txt, together with the steps that caused the issue. The log is in the game's local/crash_dump folder.
