Hello Ladylee and Welcome to MySwissAlps,
Use the Swiss Train Timetable (www.myswissalps.com/ti metable) to plan your travel. If you haven’t used it before it will pay to read the instructions on that page before delving into the timetable.
The Bernina Express bus Lugano to Tirano does not stop to pick up passengers along the route.
The Palm Express (Bus631) runs only Saturday, Sunday, Monday at that time of year. It departs Lugano at 12:00 bound for St Moritz (not Tirano) and stops at Menaggio. Reservations required.
If you want to take the Bernina Express from Tirano to Chur you are going to have to get to Lugano to catch the 10:00am Bernina bus departure (runs daily).
The Bernina timetable is here www.rhb.ch/en/panorami c-trains/bernina-express#info. Reservations are required.
If you got the Bernina bus on 28 April you could reach Zurich that night but you would have to stay overnight in Lugano on 27th most likely.
Another option for you may be to take a ferry across Lake Como to Varrena (my Italian geography is not so good) and train to Tirano.
