This weekend the Coaster is having an AWW and shutting down all passenger service between San Diego and Oceanside. During these types of events how reasonable would it be to expect to see a work train or two?
Depends entirely on the work being done.
F’rinstance, when they replace the diamond at Deshler (next week?), there will be no traffic across the diamond for most of the day - but there will be no work trains as none will be needed.
They could, f’rinstance, be doing signal work and determined it was easier to have no traffic than to have to manage it manually.
All the Coaster has described it as is “infrastructure”.
