LRT services will be suspended again on Sunday to allow crews to work on the Metro and Capital lines.
Officials said bus route 505 will replace train service and buses will stop at every station between Clareview and Century Park.
Crews will be testing the communication-based train control signaling system on the Metro and Capital lines.
This is the second Sunday that LRT service has been disrupted.
Officials said they will try and schedule further testing and disruptions so as to have minimal impact on passengers.
