Good to hear, thanks
While not a problem for the Tortoise machine, you might consider a main "kill switch" for your layout. If not for saving on your electric bill, for safety reasons.
Also, what powers your Tortoises, and how many are active on your layout?
What I'm driving at here is that the stalled motor uses more current then when the machine is in motion. If you have few dozen stalled machines and the power supply is not robust enough, it might overheat if it is always on.
