I have updated the way CMTM is installed. No longer do you need to modify the CMTMPortal or the CMTMSystem files. The new CMTMPortal4 is now a universal re-rail portal that can be used for any route, but when used on a CMTM route, it will respond to the CMTM System.
All the CMTM data has been moved from the CMTMSystem file to the config.txt file of an HTML asset. I have included a sample HTML asset which is the only item that needs to be cloned and made specific
from the wiki: For a three part hornsound, the sounds for the horn are placed in a subdirectory called 'horn'.
The lead-in sound should be named 'start.wav', the loop should be named 'idle 1.wav' and the lead-out sound should be named 'stop.wav'.
The bell sound is as for a single part or two part horn.
hope this helps
