Has anyone on the Forum had experience with the commercial helix systems offered by Ashlin? They had a new product announcement on page 18 of the May 2009 Model Railroader. See also http://ashlintrains.com.
This is probably going way overboard; however, to reduce distance between levels to a minimum, consider hinging the outer derailment guard to provide access when needed and install light beam sensors near the helix entrances to shut off power if the consist includes an oversized car or load, like they use on the cashier checkout counter at the supermarket. I would think Radio Shack might have the gear, which could be hidden in scenery, buildings, etc.
Railfan8, I like wild crazy ideas! Thanks mate.
I will consider them :D
