  • Tsunami2 Experience
    I was just at Train Shack in Burbank and Todd told me he just got in a pair of Santa Fe F7's with new Tsunami 2. I had to try them out! They SOUND AWESOME!!!! SO LOUD TOO!!!

    It was originally programmed with a single note horn, wrong for the 5-chime the engine used. BUT THEN I SWITCH TO the LESLIE RS5T and THAT IS THE SOUND THAT AL AND I REMEMBER AND HAVE BEEN LOOKING FOR!!!!

    Also just simply going back and forth on a test track with factory settings no momentum or brake set up it's SOOOOO much better than the functions of the T1!
    - Started up with the alarm bell like real!
    - First speed step I heard the brake release!
    - It accelerated with the right sound and the prime mover sounded great!
    - Horn was just like I remember!
    - Even just slowing it down without the brake set up it felt and sounded real!
    - I hit emergency stop and it DIDN'T shut it down, but you good hear the air dump! PERFECT!

    Really great job!!!"

  • Tsunami2 Motor Control
    "Dear sirs just thought I壇 run a couple of my thoughts your way. I purchased a Atheran Genesis GP38-2 a while back it came with the new tsunami2 decoder. I have serval Genesis locomotives but all of them have older tsunami decoders. I must say While I always thought you had the best sound they lacked in motor performance.

    NO MORE tsunami2 has as good if not better motor control than their competitor. I love the slow speed right out of the box and the {for lack of better words} full throttle features while never losing control of your loco. It is top notch, not to mention the new brake options /independent/train and dyno... Kudos for making the Tsunami2 it痴 great oh buy the way {don稚 hear it much anymore} proudly made in the USA."
