Wse Seminar: Stackburn and Distance to Ground in Railroad Ties

    A manufacturer of railroad cross-ties has had worker injuries related to stacking treated 10 foot ties on top of each other to build 12 inch footings mandated for seasoning wood ties. They would like to use a more convenient 6 or 8 inch footing for stacks of air-seasoning rail-ties. Moving ties closer to the ground could increase the risk of decay during seasoning, leading to weaker ties that have shorter service lives.  Leon is conducting research on the complete fungal populations in stacks of untreated air-seasoning ties positioned on different sized treated stack footings.
    This study incorporates classic mycological isolation, decay testing, genomic analysis, and strength assessments to track fungal populations over 1 year and correlate potential strength loss of rail ties to different sized stack footings.
    The results so far indicate that decay fungi in untreated hardwood ties are not affected by height above ground, but there is a distinct fungal species succession over time t. This study indicates that there is little to no benefit in using 12 inch footings compared to 6 inch footings, but that the time between seasoning and treatment is critical.
