Railroad property damage or damage to railroad property refers to damage to railroad property, including railroad on-track equipment, signals, track,track structures (including bridges and tunnels), or roadbed, including labor costs and all other costs for repair or replacement in kind. Estimated cost for replacement of railroad property must be calculated as described in the FRA Guide for Preparing Accident/Incident Reports. (See § 225.21 of this chapter.) However, replacement of passenger equipment is calculated based on the cost of acquiring a new unit for comparable service.
