With Tsunami2 Decoders you can have your locomotives auto-start when you apply power to your track or you can disable this and manually start up your diesel locomotives. We also have a quiet mode feature that you can use to minimize excess sound on your layout when you are not running a locomotive. Since steam engines take hours to 'start-up' we do not have a sound sequence or this that you can play, but you can use quiet mode in CV 113 to keep the steam locos that you are not using quiet.
