Apologies, I didn't know the systems were so different that they were incompatible. It's stupid that 2 nearly identical LRT systems being built concurrently in the same city by the same governing body would be fine to choose 2 incompatible systems.
Well, the tracks are compatible, the tunnel sizes are probably compatible as well. Full revenue interoperability may not be possible right now because of the rolling stocks, signal systems etc; but the lines are not going to be connected soon anyway. By the time they are connected, new rolling stocks will be needed, and new service contracts signed. If desired, it should be possible to include interoperability at that time.
