COASTER vs. Amtrak: which train to take up the San Diego coast
For trips inside San Diego County, take the COASTER — it stops at eight stations from downtown to Oceanside for a flat $6.50 from October 1, 2026; take the Amtrak Pacific Surfliner if you're going beyond Oceanside or want a café car, and note that COASTER day and monthly passes work on the Surfliner between Oceanside and downtown.

The short version
- The COASTER runs 41 miles from Santa Fe Depot to Oceanside in about an hour, with 8 stations including Encinitas, Carlsbad Village and Sorrento Valley.
- The Surfliner stops only four times in the county — Santa Fe Depot, Old Town, Solana Beach and Oceanside — then continues to Los Angeles and beyond, with 13 daily round trips since May 2026.
- From October 1, 2026, the COASTER charges a flat $6.50 adult one-way (it used to be $5–$6.50 by zone); youth 18 and under ride free.
- Rail 2 Rail: COASTER Regional Day and Monthly passes are valid in Surfliner coach between Oceanside and Santa Fe Depot — except on 2026 blackout dates like Thanksgiving week (Nov 25–30).
- Both trains run along the eroding Del Mar bluffs; SANDAG's long-term fix is to move the tracks inland, with a tunnel targeted around 2035.
Two passenger trains share the same tracks along the North County coast, and they serve different trips. The COASTER is North County Transit District's commuter train — frequent stops, cheap, built for local trips. The Pacific Surfliner is Amtrak's intercity train to Los Angeles and Santa Barbara — fewer stops, more comfort, and priced like Amtrak.

The Rail 2 Rail trick
If you hold a COASTER Regional Day Pass or Monthly Pass, you can ride the Surfliner in coach between Oceanside and Santa Fe Depot, getting on or off at any Surfliner station in between. That's handy when the next Surfliner leaves before the next COASTER. One-way COASTER tickets don't count, and Business Class isn't included.

The bluffs, and what El Niño means for the ride
Between Solana Beach and Sorrento Valley, both trains run along the top of the Del Mar bluffs — one of the most scenic and most precarious stretches of rail in the country. SANDAG and NCTD have completed five stabilization phases since 2003, installing more than 380 support columns; Phase 5 (about $88 million) finished in fall 2026. The permanent fix is moving the tracks off the bluff, a project still in environmental review, with a tunnel targeted around 2035.
- Stay off the Del Mar bluff tracks — trespassing on the right-of-way is illegal and deadly.
- COASTER has Friday-night trains running until about a quarter past midnight — useful for downtown evenings.
- The fare increase on Oct 1 also applies to connecting MTS buses and the Trolley ($3.00 one-way).
