I have one question in terms of the the debate between driver or driverless LRT. So far people have been focused exclusively on the savings gained by eliminating the driver. I would imagine that the introduction of the systems required to permit driverless trains also bring with them a higher cost than traditional LRT (higher precision signaling and tracking equipment, increased inspection and maintenance intervals etc...).

Does anyone have any information that looks into how these types of items may increase the cost of operating driverless trains? I'm curious because I think that when you add in these types of costs plus higher acquisition prices of driverless LRVs plus the cost of grade separating the entire Green Line to accommodate them the cost difference between driver vs driverless might be marginal at best.
