Until recently, the main track network was really inconsistent across the board. The GRSA is here to ensure consistency. This specification outlines the guidelines and requirements for utilizing the GRSA trains and track network. Please follow it, uwu.
To check if you're connected to the GRSA track network, either:
- Grab a schedule, enter a station connected to your track network, then add another and see if autocomplete suggests
GRSA Incoming
- Check if you're connected to this roundabout:
Tunnels within the GRSA track network shall have fixed dimensions to prevent train clipping and ensure smooth operations. All tunnels should be 7 blocks wide (inside) and 6 blocks high. The two corners at the top are not required. A wall in the middle, between the two tracks, is not required. However, it may be placed there, doesn't matter.

Stations should adhere to fixed dimensions, specifically concerning platform height, to ensure uniformity and compatibility with all trains.

Trains may have to travel back without interrupting other trains. If multiple tracks are placed next to each other, the track gap should be maintained. Tracks should be 5 blocks apart, tunnel or not.

Depending on the train type, the following guidelines apply:
Passenger trains operating within the GRSA network will have fixed dimensions. This includes ensuring that essential elements such as doors align uniformly with all other trains for consistent infrastructure design.
Cargo trains operating within the GRSA network shall not halt at passenger stations. Read Tunnels for size limitations. If a train serves both passenger and cargo needs, this section can be ignored. Instead, read Passenger trains. Ports shall be placed on the right, first any block, then fluids, then items.

If your train isn't automated or not meant for public use, you do not have to ensure anything but size. See Tunnels. If your train is partly meant for public use, be sure to read the above sections!
If your train is used to expand the GRSA network, make sure it is built exactly like this for consistency across other GRSA tunnels.
- Signals every 200 blocks: Place a signal every 200 blocks (at most!) to ensure smooth operations.
By adhering to this specification/ruleset, users of the GRSA trains and track network ensure a standardized, efficient, and well-maintained transportation system.
