Track types and standards

There are many kinds of tracks and standards in Anthreì City. Some tracks are elevated while some are deep underground. This is a list of all the track types and standards there are in Anthreì City.

## Metro

The tracks are of continuous powered rails.
The tracks normally go in pairs, with this pattern:
*Track, air/redstone torch, track*
Sometimes the tracks go in singular, with this pattern:
*Track, air/redstone torch* or vice versa
A 3-block height minimum is set for all of the metro's tracks.

### Ground-level

These kind of tracks have gravel below them except in Mesa biomes (terracotta) or except when crossing caves or ravines or any ditch more than 2 blocks deep (iron blocks)

### Viaduct/Bridge

When the tracks are on a bridge or viaduct, iron blocks are put below the tracks. Support beams are also built.

### Underground tunnel

When the tracks are in a tunnel (always 3×3 for two tracks), the tunnel is surrounded with stone, even below the tracks.
Tunnels below y=40 can be considered deep-level tunnels.

### Underwater tube

When the tracks are travelling straight through water, the top and sides are made of light blue stained glass while the bottom, or below the tracks, is made of iron.
Also used when crossing waterlogged ravines or caves.

### Seabed tube

When the tracks are travelling straight through water but on the seabed, the top and sides are made of light blue stained glass, similar to the underwater tube, but the bottom is made of gravel when on seabed and either stone or iron blocks when crossing ravines or ditches more than 2m deep.

## TTR

The tracks on the TTR are always underground, so there's only one type of track.
Tracks are continuous powered rails, plus command block boosters.

### Underground tunnel

The tunnels are always like this pattern:

*Stone\*, stone\*, stone, stone\*, stone\**

*Stone\*, stone stair^, air, stone stair^, stone\**

*Stone†, air, air, air, stone†*

*Stone\*, stone stair^, track, stone stair^, stone\**

*Stone\*, stone\*, stone, stone\*, stone\**

*Stone\*, stone\*, redstone torch, stone\*, stone\**

\* We do not really care about these blocks

^ On older tunnels, the stairs are made of stone bricks.

† Sometimes two tunnels are so close that these blocks are air instead and are technically in another tunnel. An example is the tunnels around Splayne station.

Each tunnel is for one track only.

## Trams

These kind of tracks are more freestyle in both terrain and standard. The tracks are made of continuous powered rails as well. They have the same standards as the Metro except for or plus these:

### Road median

The tracks line both (or one) side of the road.

For more information about the road, see Road types and standards.

### Underground tunnel

Same as the Metro's underground tunnel, but without the stone furnishing. Tunnels on the Trams are never deep-level.

## Ascending and Descending

When the tracks ascend or descend, on the Metro and Trams, the minimum is 1 block up/down for every 2 blocks forward. At the start and end of the ascending/descending part, it is 1 block up/down for every 3 blocks forward.

On the TTR, it is 1 block up/down for every 4 blocks forward, and at the start and end, 1 block up/down for every 5 blocks forward.
