When there is any resistance at all on the system the gear on the motor drive shaft ... just freewheels ... the motor turns fast but nothing else happens.

One more important point, having designed and been involved with the construction of a number of layouts with a helix, I would caution you about building a helix with such a small radius.
What will your grade be? Over 3% - plus the resistance of the curve - two of the best pulling steam locos a out there will likely only pull 20 cars up it.
