Anecdotally, CBTC is a greeat improvement in many scenarios. On long and straight stretches between express stops, trains now fly along (probably at least 40mph; never got to see inside the TO’s cab). And upon approaching an occupied station, they slow down to a crawl but keep moving until about 25-50 feet before the station, instead of being stuck several fixed blocks back before the station. Thus there is much greater track capacity = more (potential) trains per hour, and generally more reliable trips.
