DETROIT DIESEL 6V71/6V92 MEGA COMPILATION -- 4 minutes of roaring 2-stroke buses in Calgary, AB (HD)

A collection of over two dozen clips taken between 2012-2014 capturing Calgary Transit and Red Arrow Spruce Meadows buses making some sweet Detroit Diesel 2-stroke noise.

All videos were taken by me. Oldest clips are from June 2012, most recent ones are October 2014. All buses shown are long retired now with very few examples still remaining in existence.
