QUOTE: Originally posted by Jetrock I think the idea is that a second set of rails would provide current to power a winch, which could then be operated separately with a power pack. It's not really a practical idea, but it does suggest a Wouldn't It Be Cool kind of idea--that of a DCC-controlled derrick car! A set of small motors and gearings in a derrick car provides the power, and a DCC module, powered via pickups on the car's wheels, provides the control. Punch in the derrick's address on your DCC controller, and you can operate the winch! A neat idea, anyhow...
