Key features of low-cost and quickly implementable improvements. Quickly Mode Characteristics of Low-Cost Actions Implementable · Less than $1 million · Spot or location-specific improvements · No environmental clearances necessary Highways · No right-of-way acquisition Less than 1 year · No special programming required · Implementation at district lowest operation unit level (limited direct HQ oversight) · Class I railroad $1 million to $10 million Less than 2 years Railroads · Regional railroad less than $2 million Less than 1 year · Short-line railroad less than $500,000 Less than 6 months · Less than $1million Deepwater · Physical improvements may involve highway and rail projects Ports & within and outside the port terminals at links serving ports location-specific actions Less than 2 years Inland Waterways · Mainly operational actions including technology deployments · Uniqueness of each port acknowledged
