R2 replacement bus service

What is R2 service?

R2 symbol

When the O-Train is not running during regular Line 2 hours, R2 bus service may operate. R2 buses serve all Line 2 stations and only make limited stops along the way. If Line 2 is partially closed, R2 service may run only along the closed portion. ­ We will notify you in advance of any planned rail maintenance or construction. 

Routing
