Monorail/maglev Tools construct a Monorail/maglev transport network. Tools may build or remove: monorail and maglev track; bridges; tunnels; signals; depots; station-platforms; and extensions. If playing with timeline, then as time passes in Simutrans more tool options may appear.

Click monorail/maglev-icon at top of the main game window to open toolbar.
Hover the mouse cursor over a toolbar icon (after opening or clicking on toolbar) to see name and where appropriate: construction cost, maintenance cost in brackets, maximum speed limit and maximum length.

Monorail/maglev Tools include, from left to right:

Monorail/maglev Track: tools build Tracks, for monorail/maglev vehicles between two points. Tracks can only be built on slopes in the direction of the slope and may not find a path across rough terrain, water and obstructions. New Track built may use existing Track in its path.
To build Track: click on the tool icon to select Track (changes cursor to track), then click on the main game window for start-point of Track (shows a bulldozer in the main game window and map co-ordinates at on right of bottom-bar under the main game window), and finally click on the main game window for end-point for Track.
Tip: Different types of Tracks may connect (however not when built by some other players). Use Landscape tools to change terrain, to enable paths for Track. Use the destroy/remove tool to remove individual pieces of Track and some obstructions. Use [Ctrl] at same time for extra functions. Undo last route construction, [z], does not refund constructions costs.

Remove monorails: tool removes monorail/maglev Track, when no vehicles are present, between two points in the main game window (platforms and signals in path are removed too).
Use of tool incurs a construction cost.
To remove Track: click on the tool icon (changes cursor to a red-cross); then click on Track that is to be deleted (selects deletion point shown by a red cross in the main game window); and finally click at another point on track, to remove portion up to first deletion point.
Tip: Operate as another player to remove their Tracks.

Ramps and Bridges: tools build straight bridges, for monorail/maglev vehicles to pass, between two pieces of monorail/maglev Track in the main game window. Bridges have a maximum span. Tools build bridges from an end of a Track to a suitable place (another Track-end or slightly higher land, within span).
To build a ramp or bridge: click on the tool icon to select (changes cursor to bridge), then click on the end of a Track (start-point of bridge) to build. Some obstructions or lack of a suitable place for bridge-ends will prevent bridge being built: place Track at both sides that is to be bridged, and try again.
Tip: Use the destroy/remove tool to remove bridges (click on bridge-end) and some obstructions to bridge building. Use Track tools to connect bridge-ends to Track.

Monorail Signals: tools build signals for monorail and maglev vehicles on a Track in the main game window. Signals direct and regulate flow of vehicles on Tracks and bridges, junctions and Stops (where vehicles pick up and drop off passengers).
Two-way and one-way versions of signals can be built. To build a two-way signal on Track: click on the tool icon to select signal (changes cursor to signals); then click on Track. To build a one-way signal: click again at same point, with signals-cursor, to cycle through one-way signals, back to a two-way signal.
IMPORTANT: Take care not to place one-way signals that prevent vehicles reaching their destination, by default vehicles drive on the right (can be changed in simuconf.tab).
- Signals: vehicles proceed only if Track ahead up to next signal or destination in Schedule (a Stop or waypoint) is not occupied by another vehicle. In one-way mode vehicles pass in one direction only.
- PreSignals: vehicles proceed if area of Track ahead (either between three consecutive signals or to next destination in Schedule) is not occupied by another vehicle. In one-way mode they let vehicles pass in one direction only.
- ChooseSignals: direct vehicles to an empty station-platform, at a multi-platform Stop: a vehicle passing this signal may use any empty platform at its next destination, and not just the one assigned in its schedule. If no empty platform or clear route to next destination is found, then vehicles wait at signal.
Tip: Remove signals with the destroy/remove tool. Hold down [Ctrl] to place signals on bridges over lower Tracks.

Monorail Depot: tool builds a depot for purchasing and managing monrail/maglev vehicles and carriages. Depots have a maintenance cost and are built on the end of monorail/maglev Track in the main game window.
To build a monorail depot: click on the tool icon (changes cursor to a depot), then click on end of Track.

Train-stops: tools build station-platforms, used by monorail/maglev vehicles to pick up and drop off passengers and mail.
A station-platform when not built adjacent to an existing Stop will create a new Stop.
Train-stops have a maintenance cost and are built on track (but not at bends and junctions in track).
Train-stops have a catchment area for goods, passengers and mail. Different station-platforms may have different capacities for goods, passengers and mail. . In the corner of some tool options an icon (used in Station List and Stop Information) shows which items the station-platform allows a Stop to handle.
To build a a station-platform: click on the tool icon to select (changes cursor to a platform), then click on Track.
Tip: Remove train-stops with the destroy/remove tool. Extend station-platforms and build multi-platform Stops (by building more platform sections on adjacent track) to accommodate longer and more vehicles, increase capacity and catchment area. Press [v] to show/hide catchment area for goods and passengers in the main game window. Hold down [Ctrl] to build on bridges or elevated Track above lower Tracks.

Monorail Foundation:tool constructs ?an extension to a Stop and increases the capacity of the Stop. Monorail foundations are built on ends of monorail/maglev Track and have a maintenance cost.
To build an monorail foundation: click on the tool icon to select (changes cursor to foundation), then click required position on the end of a track.
Tip: Remove monorail foundations with the destroy/remove tool.
