HAVOC is a free-mo based modular layout designed for operations. Indy Junction in May of 2022 was the first time we setup for Time-Talbe and Train Order (TT&TO) operations. TT&TO was used by the reail railroads from 1860's to 1980's, so the scheme fits well with the 1920's secondary line operations of HAVOC. HAVOC is a freelanced railroad set in Ohio.
