% signal_aspect(7advtrains) | Advtrains Developer's Manual

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.
