Signal delays a daily occurrence?

Are signal delays a daily occurrence now? The past 3 days I’ve had signal delays of roughly 8-10min+ on every line I’ve been on. The driver has announced they were waiting on signals to proceed.

UPDATE: Train guard has announced are “running a slow service due to urgent signal repairs in Waverton. Currently stuck in Redfern from Burwood? Travel time so far has been 32 MINUTES for a trip that usually takes 12????? Horrendous.
