# DESCRIPTION
|
||
|
|
|
||
|
|
The signal aspect table used by advtrains has the following fields:
|
||
|
|
|
||
|
|
* `main`: The main speed restriction
|
||
|
|
* `dst`: The `main` aspect of the distant signal (not implemented)
|
||
|
|
* `type`: The type of speed restriction given by the signal
|
||
|
|
* `shunt`: Whether shunting is allowed
|
||
|
|
* `proceed_as_main`: Whether to proceed without shunting
|
||
|
|
|
||
|
|
The `main` and `dst` fields may contain the following values:
|
||
|
|
* `-1`: No speed restriction
|
||
|
|
* `nil`: No information is available
|
||
|
|
|
||
|
|
The `type` field can be any valid table index, but it should usually be one of the following values:
|
||
|
|
* "main": The main signal aspect used before the introduction of speed restriction types. This is the default value if the `type` field is absent.
|
||
|
|
* "line": The speed limit for the physical line.
|
||
|
|
* "temp": The speed limit that is temporarily introduced.
|
||
|
|
|
||
|
|
# NOTES
|
||
|
|
|
||
|
|
A signal with the `main` aspect of zero should not provide distant signal aspect.
