In 2007 and 2008, 231 of these buses were delivered after fast tracking replacement of GM Fishbowls was approved in early 2007. These buses are numbered #4523-4753. However it should be noted that about 40 diesel GM Fishbowls still remained in service after all 231 D40LFR's entered service. The interior features are very similar to 2005 New Flyer D40LF's.
In the second half of 2009, 121 more of New Flyer D40LFR buses were delivered and numbered #4754-4874. A final bus in 2010 (#4875) was delivered. These buses are distinct from the 1st order because of a more squared off door design and a slight rounded curve on the bottom corners of the front windshield. This second order also features updated seats.
The buses are powered by Cummins ISL engines and Allison B400R transmissions. Luminator Horizon LED destination signs like previous orders of D40LF's are also included. These buses also include a small display box located in the front windsheild next to the front door. The box can display various messages such as express or school service, though they often just display the route number.
