It is frustrating to know that up until the 1950s Christchurch had a mass transit network of trams running on electricity. Imagine an alternative universe where this system was kept, updated and extended into new suburbs. It might now serve the airport, University, and the new suburbs towards Halswell.
But instead they were ripped up and replaced with busses. I've posted previously -

Christchurch, New Zealand - scenes and trams from early 1900s - tells it better. Enjoy.
