What time you need to leave your desk to make the train.
The schedule on file has expired.
One-time setup
Travel times are looked up once, now, and cached. Your addresses stay in this browser.
Found these
This is how the map read your addresses. If either is not your building, fix it before saving.
Buffers
Plus one fixed minute: GO doors lock one minute before departure. That is the train, not a preference, so it is not a slider.
Your addresses, station, and buffers are saved in this browser only. They are never written to a server.
At setup, your addresses are sent once through this site to Google Maps to measure the walk to Union and the trip from your station home. Google returns durations; nothing is kept on this site's server.
Each answer sends only your station code to the schedule database. Standard usage counts are logged like every other tool here.
