The new Kitchener Line schedule still isn't on the website yet, which is unsurprising given the change was sprung on GO by politicians outside of the normal planning cycle, to fix an issue most likely caused by politicians springing half-baked ideas on GO outside of the planning cycle.
Anyway, if the 16:50 train is reinstated on its previous schedule, there will be reliability problems because the new 16:35 train is literally in its way. The express train is supposed to be 12 minutes faster than the local, which means that if it departs 15 minutes later, it will arrive at Bramalea only 3 minutes behind. At which point even the slightest delay to the 16:35 will cascade onto the 16:50. Ideally the trains should be spread further apart if there are slots available to do so in the USRC, perhaps shifting the 16:35 to 16:30.

And on an unrelated note, the current schedule has the 17:40 VIA overtaking the previous GO train at Malton at 18:00 (previously they met at Brampton), which is probably a good idea given that it simplifies operation on the CN segment. But the VIA is scheduled to stop at Malton, which makes it quite difficult to overtake the previous train within the relatively short segment of double track between Bramalea and Pearson Junction. I think Malton should be dropped from the VIA trip since hardly anyone ever gets on there anyway, there's plenty of GO service to carry people from Malton to Brampton where they could pick up the VIA, and stopping the VIA train makes the schedule quite tenuous.
If the new schedule does in fact mean a 6th train runs to Kitchener, then there should presumably be a 6th train coming back eastbound. My votes are either to provide a new express trip during the 30-minute gap in the peak period, or to extend the first off-peak trip (which currently deadheads from downtown anyway), to replace a bus trip which currently gets stuck in rush-hour traffic and extend the service hours toward the realm of reason for people who aren't commuting to an office in downtown Toronto.
