It works very similarly to Construction mode with some add-ons in the building bottom bar:

• Stations: Build a station sign & configure it (middle mouse button or V key) to set name, serviced traffic types and probability weights for contract generator (relevant for Endless maps)
• Platforms: Build a Platform on an existing track & configure it (MMB or V) to build Sinks or reassign it to some other station
• Auto Blocks: Convert existing tracks of any length and shape to Auto Blocks

System Upgrades offers configuration of System Upgrades for the game:

• For Endless mode: Configure upgrades installed from beginning & upgrades not available at all.
• For Timetable & Rush Hour mode: Select upgrades enabled during the game; As majority of upgrades is bound to Endless gameplay (i.e. unlock some building), only some unlocking is effective actually.

In the UI known from Play mode it is possible to

• For Endless mode: Create initial contracts the Endless game starts with
• For Timetable mode: Create the complete timetable of the map
• For Rush Hour mode: Create schedule prototypes for randomly generated traffic - traffic generator does not make up schedules, only chooses from the pre-defined ones

Note: Applicable on Endless mode maps only.

Contracts are randomly generated in Endless mode. Map creator can affect it by configuring traffic probability weights per station & traffic type. Middle-click the station sign to enter the configuration.

The relative weight (importance) determines which stations are included in randomly generated contract offers of the type. A higher number means that this station is more likely to be included in a contract offer.

For example, a weight of 4 means that this station is twice as likely to be included in a contract offer as a station with a weight of 2.

If weight is set to 0 for some contract type, the station is never generated as an origin / mandatory stop / destination of an contract of that type.

Other rules apply as well in the contract generator, so the contract distribution may not perfectly match the weights:

• Contracts are generated to non-active stations but with lower probability
• Stations that owns the contract (Station the Office is associated with) is enforced to be part of the contract
• Shorter contracts are preferred over longer by generating the max distance first & then generating a contract that fulfils it.

To create the map for Rail Route:

1. Click Add map → Editor in Main menu
2. Configure Map name & dimensions (Width & Height). Beware that dimensions can not be changed afterwards. Click Create map
3. Configure _Game mode_ & other relevant properties of your map
4. Laid Tracks, build Signals etc
5. Laid the layout of a station (just Tracks & Signals)
6. Build a Station Sign near your tracks.
7. Middle-click it to configure its name & traffic type probability weights
8. Build a Platform on each of the station tracks where trains should stop. Platform is auto-assigned to the nearest station.
9. Middle-click the platform to build Sinks (points where train enter or exit the map) or re-assign the Platform to other Station
10. If an Auto Block is needed, build a Track first, select Auto Block in Construction and click the pre-build track to convert it to an Auto Block
11. Configure System Upgrades if needed (see System Upgrades section)
12. Create the traffic (see Contracts section)
