what would be the advantage of stopping Milton trains at Bloor station?
A direct shuttle bus from Dixie would address the potential airport traffic. People getting on the subway at Kipling are guaranteed a seat, whereas people getting on at Dundas West will stand (and by then, the trains are pretty crowded at rush hour).
The current peak point on the line is between Dixie and Kipling, not between Kipling and Union. With the exception of the first and last trains, anyone getting on at Kipling today is going to not get a seat anyways.
Putting a stop here makes intuitive sense, but I wonder if the numbers bear it out. Suppose 10% of customers coming from Dixie or beyond would alight at Dundas West if it saved them say 5 minutes over subway from Kipling. The other 90% - who do want the direct ride to Union - have 4 minutes added to their trip downtown. Is that a good tradeoff?
If you're heading to/from Etobicoke North, Weston or Bramalea then a quick change of platform would likely be better than schlepping from Dundas West TTC to GO as I did the other day. Being above ground is more generally enjoyable than being under so people heading to UofT etc. might appreciate the shorter period of gloom/bad AC/dodgy wifi. Even without the inter-station walk, if the gap between GO and subway is only 6 minutes, then for a 2 x 5 commuter that's an hour a week. More passenger footfall might also mean a few more facilities at the currently spartan Bloor GO station.Looks like +/- 6 minutes of saving for a very few people (subway takes 14 minutes Kipling to Dundas W.....GO train Kipling to Union takes 20 minutes....GO train Bloor to Union takes 12 minutes...so we can estimate from schedules that GO Kipling to Bloor is about 8 minutes).
Like you say, is that saving of 6 minutes for a relatively few people worth adding a few minutes to the commute of many? Is it worth the expense that would be required to make it possible? Does having more trains stopping at Bloor Stn from more lines make it harder/more expensive to make room for more frequent service on the line that currently stops at Bloor? These are technical questions beyond me....but my gut says to me that it does not seem to be worth worrying about....it really adds very little in the way of connectivity.
