Appeals court affirms decision on spat over communication lines running beneath train tracks - The Indiana Lawyer
A federal appeals court affirmed a lower ruling that CSX Transportation cannot block Zayo Group from installing fiber optic cables beneath CSX railroad tracks, according to a 7th Circuit Aug. 7 opinion. The court said Indiana railroad easement law covers the corridor surface, not air or ground below, and found no “continuing trespass.” CSX’s claims were also limited by statute of limitations.
How this was made
The 30-second read
Why it matters
The appeals court held CSX’s easement rights under Indiana law did not cover excluding third-party fiber installs above or below the corridor, did not support rent collection, and did not meet the standard for continuing trespass. It also affirmed statute-of-limitations limits on older criminal trespass and licensing theft claims.
Market read
This is a legal precedent update that reduces uncertainty for Zayo’s corridor fiber strategy and limits CSX’s ability to block similar third-party telecom infrastructure absent operational interference.
What to watch
The article does not quantify damages or ongoing licensing economics, so traders may overestimate financial impact versus legal-risk signaling.
Background
CSX sued Zayo in 2021 over alleged unauthorized fiber installations beneath railroad corridors in Indiana and related Illinois claims; the district court partially dismissed and the 7th Circuit affirmed.
Ticker impact
7th Circuit affirmed that CSX cannot block Zayo from installing underground fiber beneath its tracks, rejecting CSX’s easement and continuing-trespass arguments.
Likely limited near-term impact on CSX shares; more relevant to legal risk and future corridor licensing disputes.
The decision is specific to a dispute with Zayo and does not cite operational disruption, but it constrains CSX’s enforcement posture and rent/licensing claims.
Market effects
Reinforces precedent that railroad corridors can be used by telecom utilities for infrastructure without exclusive-use easement rights, potentially affecting future right-of-way disputes.
Indiana-focused easement interpretation may influence similar corridor litigation in the 7th Circuit region.
Limited, as the ruling is jurisdiction-specific and tied to a particular corridor dispute.
Counterpoint
Even with the ruling, future disputes could still arise on different easement language, construction methods, or demonstrated operational interference.
