Good point regarding the difference in speed between the 169 and the Evergreen Line. From what I remember, to address this issue Translink is planning to add more stops along Lougheed for the 169. Unfortunately I can't manage to track down the original source right now, but this
news article mentions Translink wanting to increase the number of stops. However, I have no idea how much time this will add to the trip.
So the Evergreen line will most likely be the fastest way to get to Coquitlam Station.
