I'm in the camp that believes the lack of evening trains plays against midday ridership. Not to mention that even now, on evenings and nights of significant events downtown ie. Sports, major concert, it's a circus trying to cram in all the extra bus services (which are usually still not enough), having people packed into standing room only buses that get stuck in traffic on the Lakeshore/Gardiner promptly upon departure from the terminal, where even at 10-10:30pm a 40 minute scheduled trip can take twice as long. On weekends, I currently drive to Kipling or Long Branch from Brampton to catch a train (subway) when heading into downtown and I always get a kick out of whizzing by traffic on the Gardiner, including the odd Go bus, especially around the West Beaches.
I thought the goal was to provide an alternative to driving/being stuck in traffic. Unfortunately for Go/ML the lack of things like even fair train service has contributed to the car culture around the GTA. The only way to begin to turn the tide is to implement said train service asap. The longer it takes for that to happen, the longer it's going to take to shift people's preferences away from the car. At some point we are going to have to accept that ridership isn't going to skyrocket overnight. Besides, I am on those midday trains at least a couple of times per week and the six car trains (Union bound) are generally 30-40% full, except maybe the last two trips (the expresses). Out of nearly 1000 seats. For a truncated service, I don't judge that to be all that bad.
Very disappointing that all that infrastructure we spent half a billion dollars on continues to sit underutilized when we so desperately need these trains activated.
