The North County coastal rail corridor was scheduled to shut down this weekend for construction, impacting Amtrak and Coaster train service, according to the North County Transit District.
This weekend will be the first of three January rail closures. The others will be Jan. 16-17 and 23-24, the NCTD said.
Crews will work on replacing bridges and aging trestles over the Los Penasquitos Lagoon, and installing a crossover track.
Amtrak plans to cancel three trains, and will offer bus service between San Diego and Oceanside, and Solana Beach and Oceanside.
The NCTD said it doesn't plan to offer replacement bus service, but suggested that Coaster users could ride the Route 101 bus.
The work is scheduled to begin on each Saturday at 12:30 a.m. and continue until Monday at 3 a.m. -- with service resuming for the morning commute.
The agency warned that there will be periods of substantial noise in the Los Penasquitos Lagoon area because of the construction work.
