Sigsys name
The first line tells the name of the signal system.
These lines are the info text, which is brought up
by pressing the "Info ->" button in the route options
screen. This section is ended on the next line:
#end#



The next section contains the csv-commands for
setting the speed limits for different warning
aspects of the signals:

#speeds#
Route.Signal(1) 250
Route.Signal(2) 250
Route.Signal(3) 250
#end#



This section defines the text, which is to replace
all the original signal commands in the selected
route. This example maintains the original form
of the signals (type, position, name etc.)

#signaldef#
s a p n p x p y p t e
#end#



Here is the definition of the relays, otherwise
it works in the same way as the signaldef section.
You could e.g. write only a blank line between the
section start and end commands. This would replace
all relay commands of the original route with an
empty line, thus removing all relays. This example
maintains the original form of the relays.

#relaydef#
r x p y e
#end#
