Trains

Trains is a common mean of public transport in Tunnelers' Abyss. It uses the publicly available mod advtrains. Building custom track within an own base is allowed without any additional restrictions, building tracks outside an own base is restricted by the ministry of transport. A license for building railways can be obtained in the TA Transit Office, which is located in Grapeyard Superb, Truncated Icosahedron Street 0.

Tunnelers' Train Transport Limited (TTTL)
Tunnelers' Train Transport Limited is the company which owns the majority of railway in the world, especially the railway tracks connecting different towns.

Grapeyard Superb Metro Rail Limited (GSMRL)
Grapeyard Superb Metro Rail Limited is a company whose connects various towns in Grapeyard and some towns and places outside Grapeyard.

Haraburg Transit Company (HTC)
Haraburg Transit Company connects Halvosia with Monto Kastelo and Khorioberg and other nearby places. Etablished in Haraburd, it belongs to TTTL.

Tommy Rails
Tommy Rails is a small company which owns the Spawn Underground and a line connecting Hispania with Tommyland.

Abyssalia
The southern Abyssalia is densely connected by railway. However, there is no railway on the north of Cosine Valley.

Legendria
Legendria is the second continent which hosted train transport. The legendrian network is connected to Abyssalia via a bridge to Mandelbrot Peninsula. The railway is concentrated on the western coast and the line R2 spans Legendria up to Docker.

Besselia
Besselia has only a few short operational railway segments. There was an attempt to connect Pyleyard with Southern Cliff via Revenge for Pedestrians. Some railway was placed but the player working on this got banned shortly after.

Haraburd
Peak Transport built some tracks in Haraburd. The main line lead from East Coast Desert to Mountain Refuge. It was partially deconstructed because it was supposed to be built in better quality.

Common mistakes in building railway tracks

 * curves too sharp - The curves should be always as large as possible. Plan the trajectory first and when you like it, build the track there.
 * steep dirt cliffs next to tracks - The slope of crumbly materials should not exceed 45 degrees. If satisfying this constraint would lead to massive destruction of terrain, build a solid wall.
 * wrong material put bellow tracks - Do not lay tracks on dirt, sand, leaves etc..
 * bridges lacking pillars - There is a difference between a bridge and a flying railway.
 * bridges too low - The space bellow the bridge should be at least 3 nodes high. If not, fill the space bellow the track completely by a crumbly material.
 * bridges built where it's not neccessary - Maybe you do not need to build a bridge if you built the track slightly aside. Be careful when planning the trajectory!
 * unable to sail bellow a sea bridge - Bridges over sea should be high enough so it is possible to sail bellow them.
 * tunnels built where it's not neccessary - Maybe you do not need to build a tunnel if you built the track slightly aside. Be careful when planning the trajectory!
 * tunnels too shallow - The inner height of a tunnel should be at least 4 nodes. Then there should be a layer of a solid material and then there should be at least one layer of the ground material. That means, the elevation of track and the terrain must differ by at least 6 nodes. If it is not the case, remove all the ground above the track.
 * tunnel walls not reinforced - To build a tunnel, mining out the rock is not enough. The walls and ceiling should be made of a solid material.
 * track placed slightly above or slightly bellow the level of terrain for no reason - The track is built in the level of terrain if and only if it is possible to walk onto the track and back without the change of the y-coordinate. Build the track at the level of terrain as often as possible.
 * rollercoaster built instead of railway - The maximum slope of track in the reality is about 30‰. In Minetest, the flattest slope track has slope 333‰. To build realistic tracks, place the slopes sparsely. And do not use 2-nodes long slopes except the diagonal ones.
 * platforms too short - The platforms should be at least 30 nodes long. Platforms for local transpot can be shorter.
 * track not traced optimally - Plan the trajectory first and do not build the track until you are sure that it cannot be better.
 * stations encased in cobbleboxes - The station building should be aside the track, not all over the track. Encasing stations into buildings is reasonable only for really large stations and not even all of them.
