3D Train Studio uses the term “depot” for what English railway modellers would understand as a fiddle yard.
Many model railway layouts work with fiddle yards to park trains out of the field of vision. From 3D Train Studio v7 onwards, this feature can be simulated with the help of virtual depots and portals, without having to lay tracks or points for the fiddle yard.
This German language video explains how portals and fiddle yards work in 3D Train Studio.
A virtual depot can be found in the online catalog category traffic routes / virtual. This is placed at the end of a track and clicks into place automatically. As soon as a train reaches the depot, it disappears from the system together with all of the cargo and is stored in the depot. Using the properties window of the depot, trains can then be specifically released from the depot.
Trains or vehicles can also be sent to any depot with a click of the mouse. To do this, a vehicle is marked and then assigned to a depot using the house symbol in the properties window.
Of course, trains can also be released from depots via Event management management.
In practice, depots are often combined with portals. A portal creates a virtual connection between two track ends. Place two portals, one at each end of the track, and connect the two portals to create a connection. If a train or a vehicle enters one portal, it comes out automatically at the other portal, car by car. Portals are therefore suitable, for example, to move trains quickly to another level within tunnels, for example to save complicated track constructions to the tunnel exit or to allow the train to enter a virtual depot afterwards.
