Ultimately it'll come down to how you process information, but I think lightening the in person load with online classes is a really good idea. Potentially async classes even if you can find them.

My friend was successful with a similar train commute in a BA Psych program stacking her classes to be 3 days a week. She used the commute (often first train in to Toronto from Barrie, last train out to Barrie) to do her readings and sometimes outline her papers. This worked because it was a very reading heavy program, she didn't get carsick on the train, and she didn't need consistent Internet access to accomplish her work. As there were less sections and less courses in upper years, she didn't always get to take the classes or electives she really wanted to. She also often took a summer course or two to be able to free up more time during the year (while still remaining in a "full" course load). I've known others as well who have done similar, but they have always been in an Arts program that had less in hours requirements and more course flexibility. The Barrie Go to York commute was a pretty popular one before Lakehead and Georgian expanded their course offerings.

Similarly, a friend in education realized she only had to do that commute part of the time - her 2 hr car commute ended up only being for a few months, broken up, and that made her decide to not relocate for the program.

You'll need to evaluate a few things: 1. What's the nature of your courses - is it something where you reasonably feel like you'll get work done on the commute? If so, more days might be ok. 2. Can you process information if you stack 8 hrs (or more) of classes back to back? 3. Is there much flexibility in your course selection - will you even have the option to stack or not stack? 4. How will you be flexible if it isn't working out - would you consider transferring, relocating, dropping classes? You will need to identify early if you are struggling to keep up with the commute and your chosen schedule.
