|Build track above tunnel entrances||Not done||Done||All Track directions allowed. Automatic track construction for depots also supported.|
|Working Multiplayer (en)||Done||WIP|

|Yet Another PBS Patch (en)||Done||Done|
|New Pathfinder (en)||Done||WIP||Being worked on by Eis_os|
|Routing restrictions at signals||WIP||Done||The MiniIN restricts based on maximum speed, with global settings (fast/medium/slow). TTDPatch restricts based on one or more of power, weight, length, next order, maximum speed, and nearby signal status; combined with any combination of or, and, and xor; with per-signal settings.|
|Programmable Signals||WIP||Done||Allows the User to restrict the passage of Trains based on the state of other signals, station platforms, etc. For example, if a Mainline signal is red, the branch line signal can be set to automatically go red and therefore allows Priority to be given to certain tracks. See TTDP Wiki|

|New signals||Not Done||Done|
|New objects (eyecandy)||WIP||WIP|
