49 C.F.R. § 219.10
Any person, as defined by § 219.5 , who violates any requirement of this part or causes the violation of any such requirement is subject to a civil penalty of at least $1,086 and not more than $35,516 per violation, except that: Penalties may be assessed against individuals only for willful violations; where a grossly negligent violation or a pattern of repeated violations has created an imminent hazard of death or injury, or has caused death or injury, a penalty not to exceed $142,063 per violation may be assessed; and the standard of liability for a railroad will vary depending upon the requirement involved. See, e.g.,§ 219.105 , which is construed to qualify the responsibility of a railroad for the unauthorized conduct of a regulated employee that violates § 219.101 or § 219.102 (while imposing a duty of due diligence to prevent such conduct). Each day a violation continues constitutes a separate offense. See FRA's website at www.fra.dot.gov for a statement of agency civil penalty policy.
