In 1998 ETS received 80 new D40LF low floor buses from New Flyer. These units, #s 4046-4125, were the first full-sized buses delivered in the blue and silver ETS scheme. They featured Balios orange LED destination signs and Thermo King rear-mounted heating units, and were the first buses delivered with New Flyer's warm (inner) wall heating system. These buses were powered by the Cummins C8.3E engine and the Allison B400R5 transmission. #4110 was in a head on collision with #953. 953 was retired, while 4110 had its front end rebuilt at Westwood, and has since returned to service. #4112 suffered a major engine fire in June 2006, and was subsequently sent to Winnipeg for rebuild. #4086 suffered a major engine fire in August 2014, and ETS chose to retire it rather than rebuilt it at that point in its life (16 years of service). #4084 and 4121 had newer-style Pocatec orange LED destination signs on the front only, and #4106 was the only unit to have its engine upgraded to a Cummins ISL in place of the original C8.3E. Almost all of these buses had their interiors updated with blue ETS insignia seat inserts. All remaining units were equipped with Smartbus GPS & stop announcement systems in 2016. The majority were retired in 2018 upon the arrival of 110 New Flyer XD40's. Around 40% of the fleet survived into 2019. #'s 4105 & 4120 were the last in service, retired in March 2020.
