making 41 stops at Aldershot GO and eliminate 18
As title states, route 41 is already insane in both length / end-to-end runtime and frequency, and the route passes Aldershot GO without stopping, in the meanwhile route 18 provides service from Aldershot GO to Hamilton GO Center without stopping at McMaster U.
I understand that route 18 exist as a last-mile delivery of LW Hamilton GO Center branch, but since trains are stopping at West Harbour with an hourly basis, I believe the amount of passenger who take 18 to train does not need one dedicated bus and instead can be fit into route 41, Also route 41 is passing McMaster so it provides one more source of passenger to optimize the usage of this route.
Route 41 is already lengthy enough so it's in a state which adding one more stop won't create significant difference in travel time, and i believe there are very few passengers take the route from end to end. Also, by making some rush hour route 47 stop at Aldershot it could also relief the pressure from route 15.
With 41 and 47 stop at Aldershot, route 18 could be eliminated and all its trips will start/end at Union which serves only when the entire LW is not running. Just like how today's route 31 and 33 serving Kitchener Line works where 31 have only a few early morning / late night departure and 33 covers the area not served by train mid-day but go beyond and terminate at York Mills.
