# Description
This page describes various fields in node definition tables that are used by Advtrains.
# Node Groups
Advtrains uses node groups to identify certain properties of a node. The following node groups are currently read by Advtrains:
* `advtrains_signal`: When set, this property defines the type of signal this node belongs to. `1` indicates that this node is a static signal, and `2` indicates that this node is a signal with a variable aspect.
* `not_blocking_trains`: When set to 1, trains can move through this node.
* `save_in_at_nodedb`: When set to 1, this node should be saved in the internal node database used by Advtrains.
# The `advtrains` Field
The `advtrains` field in the node definition may contain the following fields:
* `get_aspect(pos, node)`: This function should return the signal aspect of the node at the given position.
* `set_aspect(pos, node, asp)`: This function should set the signal aspect of the node to `asp` if possible. `asp` is not guranteed to be an aspect supported by the node.
* `supported_aspects`: This table should contain a list of supported signal aspects.
