Short on resources to upgrade your entire factory? Or want to upgrade just one specific belt or pipe line woven into a dense spaghetti base?

Belt Line Upgrade lets you select a single segment to instantly queue an upgrade, downgrade, or deconstruction order across the entire connected line!

Features & Tools

All tools are accessible directly from your shortcut bar / toolbelt.

1. Belt Line Upgrade Tool (Tiers)

• Left Click: Upgrade the connected line up one tier (excludes sideloaded feeder belts).
• Right Click: Downgrade the connected line down one tier (excludes sideloaded feeder belts).
• Shift + Left Click: Upgrade the line and all upstream sideloaded feeder belts.
• Shift + Right Click: Downgrade the line and all upstream sideloaded feeder belts.

2. Belt Line Quality Upgrade Tool (Quality)

• Left Click / Right Click: Upgrade or downgrade quality levels across the connected belt or pipe line (Normal → Uncommon → Rare → Epic → Legendary).
• Supports Space Age and standalone Quality mods.

3. Belt Line Deconstruction Tool

• Left Click: Mark the entire downstream line for deconstruction.
• Right Click: Cancel deconstruction on the connected line.
• Upstream Protection: Deconstruction automatically stops at upstream splitters to prevent accidentally tearing down other shared factory inputs. Use Shift + Left Click to force deconstruction through splitters.

Built-in Safety & Quality of Life

• Sideload Isolation: Regular clicking isolates the main transport flow and ignores perpendicular incoming belts, preventing accidental main-bus upgrades.
• Belt-Weave Conflict Protection: Intelligently prevents upgrading or downgrading interleaved underground belts if the new tier or quality would collide and break your weave.
• Underground Range Validation: Prevents downgrading underground belts and pipes if the lower tier's max reach is shorter than the active span.
• Undo & Redo Compatible: Fully supports standard Ctrl+Z and Ctrl+Y actions.
• Floating Feedback: Immediate localized cursor notifications explain if a line is already at max/min tier or if an action is blocked by a safety rule.

Supported Entities & Mod Compatibility

• Vanilla & Space Age: Belts, Underground Belts, Splitters, Loaders (1x1 & 1x2), Pipes, Pipes-to-Ground, and Pumps.
