Building a helix significantly larger helix than 32" radius will limit the aisle space at Ravenswood with multiple operators. (Grantsville is above Ravenswood) If that water heater ever fails and needs replaced, it is going to be hard enough to get it past the East end of Ravenswood near the yard lead. I'm not overly concerned with maintenance access in the helix, I have worked in helixes of similar height between the loops without too much trouble. Also, the 3/4 of the helix would be accessible externally, hidden by fascia. I've really got to get the new track plan up. Sent from my PantechP8010 using Tapatalk
