The southbound platform at the Burlingame Caltrain station is closing today as part of the agency's project to renovate it.
For the duration of the closure, which will last between four and six weeks, southbound passengers will board just north of the current southbound platform, behind Royal Donuts, according to Caltrain.
Conductors and station signage will inform customers about this change.
The platform is being closed so construction crews can use heavy equipment to install a new drainage system in the boarding area, according to Caltrain. The construction will not affect train service.
When the station upgrade is completed this summer the center platform at the station will have been eliminated. New outside boarding platforms will be constructed and a fence will run between the tracks to prevent trespassers from crossing.
