Helix Track Design
Helix tracks allow the train to move up and down extending a two-dimensional into three dimensions. Below is information on novel helix designs used with O-guage trains.
See photos and information about the SSPRR Run Room Helix.
Double Helix
This was my first helix. I bought it at a RMDTCA estate auction in about 1989 for $35. After running trains on it at a lot of train meets I sold it to a TCA member from New Mexico. That TCA member had bid against me at the auction but couldn't take it home with him because he was travelling in a Thunderbird. He was very happy to be able to finally purchase it to run in New Mexico.
