Formed in 1980 from the merger of Chessie System and Seaboard Coast Line, the railroad operates roughly 20,000 route miles across the eastern United States, serving ports and industrial corridors from the Midwest to the Atlantic. Hunter Harrison brought precision scheduled railroading here in 2017, cutting assets and headcount sharply before his death that year. Coal has declined as a share of freight while intermodal and merchandise have grown. Headquarters are in Jacksonville, Florida.

Equity comp at CSX
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

CSX equity questions
- How much CSX stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your CSX position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does CSX grant ISOs, NSOs, or RSUs?
- Equity compensation at CSX typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do CSX RSUs use double-trigger vesting?
- No. CSX restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
