The design of this extra special project required the engineering team at PCP to create a train tunnel designed and constructed out of CSP. While there are currently 4 different tunnels located at Bitter Creek Railroad this track was the first type designed and built with corrugated steel pipe!
The pipe was installed in a location containing sugary sand so a constant re-excavation of material to accommodate the trend installation was required. A CAD design was used to ensure proper clearances and cuts. Finally, polyurethane spray foam was applied to joints and then wrapped with a woven mono-filament fabric to maximize the seal.
