The northbound 510 is listed as a Service Disruption. Presumably if the equipment is in SEA they could still run the train
with a 90-minute delay
The latest tweet has good news and bad news.
Amtrak Cascades @Amtrak_Cascades
Cascades service 510 to Vancouver now 38 mins late departing in Stanwood - will be delayed further due to mechanical problem.
Looks like 510 is being annulled in Bellingham with a bus to VAC, and this evening's 517 VAC-SEA is being replaced by buses. But mudslides
aren't the culprit this time...it's a mechanical problem. Rough week for the northern end of the Cascades line. Fortunately most of the service
from SEA-south this week seems to have run OK, except for some weather delays on Monday.
The overnight non-stop "red-eye" from SEA-to-PDX on Wednesday night departed SEA on time and arrived into PDX 37 minutes early at 3:37 A.M.
