TL;DR:

The steepest tramway with only wheel/rail adhesion was in Montreal (14%), which the replacement buses could not manage in winter.

For reference, this is what a 14% incline looks like. Nothing to sneeze at, note the drastic slowdown and the change in engine sound of the truck.

    Some busses have in the middle a more flexible connection, which allows them to get considerable tight corners.
