With 4G being common nowadays, about time ktmb consider updating their signalling system to wireless

You need the signals the whole railway line? No, you just need it for communications between stations, for train tracking and positioning. And all stations are located in populous area where mobile signals are present.

Plus the train line involved here is peninsular west coast route. Our west coast is the most populous area. How many places along the route would be out of signal? There is no way a repeater tower can't cover the blind spot - just need to invest money to build. With the repeated thefts and losses, the value is already more than enough to cover the building of such facility.
True, BUT with the constant and repeated thefts of cables, is it worth it or not to start investing and building an alternate and modern wireless system? 4G bandwidth nowadays exceed the capabilities of wired broadband 20 years ago, which I believe that KTMB is still utilising as of today. Plus ktmb is not sucking Gbs or Tbs for their signalling Comms anyway.

By wireless it's not just depending fully on mobile network, we still have satellite and age-tested HF radio that could serve as backup. It all falls back to whether organisations involved is willing to or worth to invest the moolah to build and move to a different system

Yes
