This comment is based on the earlier post Greenfield / Brownfield. It notes that the trench option will be extremely disruptive to operations for four years or more. This will not only cause many delays to passenger service along the corridor, it will also negatively impact the operations and profitability of CSX and other freight companies.
A bypass, on the other hand, can be installed without causing any disruption to on-going operations.
