Trains on Tram Tracks

Some modern trams can already run on train tracks, but trains have never been allowed on tram tracks. Trains on Tram Tracks opens both networks to each other: every train can use tram tracks, and every tram can use train tracks, just like light rail.

Run a freight train down the main street to a factory in the middle of town, use the tram tracks you already have to bring trains into the city centre, or send your old trams out onto the railway.

What it does

• Trains on tram tracks: trains can drive on any tram track: standalone tram tracks, town streets with tram tracks, and streets you upgraded with the tram tool. They can stop at tram stops and be assigned to tram lines.
• Trams on train tracks: every tram becomes light rail, the same way the game's own light rail trams work. They can run on train tracks and stop at train stations.
• Nothing else changes: trains are still bought in train depots, trams in tram depots, and multiple units work as usual.
• Works with modded trains, trams and tram roads.

How to use it

• Enable the mod. By default it works both ways. In the mod's settings you can limit it to trains on tram tracks only or trams on train tracks only; the choice takes effect when a game is loaded.
• Connect your tram tracks and train tracks where you want vehicles to cross over, then build lines as usual. Trains show tram lines when you send them to a line, and trams can be routed over the railway.

Good to know

• Electric vehicles still need overhead wires. Electric trains can use tram catenary and electric trams can use train catenary. Steam and diesel vehicles go anywhere.
• Depots: because trains can now use tram tracks, the game might send a train to a tram depot. The mod catches that: the train carries on along its line for a moment and is sent again, so the game picks a train depot further on. In the rare case that keeps failing, the train is moved into the nearest train depot just as it reaches the tram depot. This also works for trains sent to a depot by other mods, and buses, trams, ships and aircraft are left alone.
• Because a train is now both a train and a tram, the game writes an "Invalid number of carriers" error to its log when you buy one. The train is bought and works normally. You'll only see this as a red error box if you play with debug mode turned on, which some other mods require.

Adding and removing

You can add the mod to an existing save. Removing it is safe as well: nothing in your save depends on it. Vehicles that were using the other kind of track simply can't find a route anymore, so move them back to their own tracks or give them new lines.

Compatibility

The mod adjusts which tracks vehicles may use while the game loads, and a small script redirects trains away from tram depots. It doesn't change any buildings, depots or the interface, so it should work alongside most other mods.
