    This shouldn't be any issue. Certainly the more grip you have the better, so putting traction bands on the blind drivers as well will help with this, but driving through blind drivers is not a problem for coupled axles. My GT3 model is set up this way and the rods just transfer the drive to all three axles.

    Hello Hod

    I was just reading the above message and wondered if I could clarify something. Your GT3's axle are only coupled by the external rods and only the middle axle is driven by the motor? Do you have some photos to show your design there?

    Thanks

      Hello,

      Thanks for the message. I had to try and track down which discussion you had taken the quote from, but I found it now. :classic:

      I don't have any photos of the GT3's drive to share, but I can confirm that the gears from the motor(s) drive the middle axle and that drive is transferred to the other two axles only by the external coupling rods. This seems to work perfectly well even if the middle axle has flangeless "blind" drivers. It's the same system of drive used on many real locomotives (including the GT3). It's just that the arrangement of the motors and battery box inside the model means that I can only get the drive down to the middle axle.

      I hope this helps to answer your question.
