Seems that theres been a failure this morning between T123 and T5
according to the traffic news. Can't even virtually brand new signals
work without failing on this system? Whats the reason, cheap
components, poor maintenance, bad design?

Bad luck?

Luck shouldn't come into it. These systems are supposed to be
professionally built and maintained. There might be an excuse for
endless failures on older bits of the system but this was only opened
last year.

You can reduce failure rates with high quality production and
maintenance, but you can't eliminate them. A single failure doesn't
tell you much about the quality of the underlying system.
