It has been widely accepted that of rebuilding the New Flyer D40 was not cost effective by Calgary Transit standards in comparision to rebuilding the GM New Looks and MCI Classics. This realization came to being only after #7001 had been rebuilt. The majority of the less then 100 hundred remaining New Flyer D40's in Canada operate for Winnipeg Transit. However, Calgary Transit's #7001 is among one of the various examples of small fleets of New Flyer D40's that still exist.
