Indeed. My lab is on East Mall and our electron microscopes can be perturbed by the movements of elevators so we have to use them mostly in the evening. Also, Main Mall north to Univ Blvd are the Physics/Astronomy and Chemistry Departments and they wouldn't like the idea either. Unless they know what they are doing and are able to minimize the effects. Meanwhile, I am not able to come up with a better location of a UBC station inside the campus. Plus I will have almost certainly left UBC by 2025...... Edit: I doubt if they will go as south as TRIUMF. Terminating at Wesbrook Village could be a good idea.
