During the summer of 2002, ETS began taking delivery of 53 D40LFs from New Flyer. Powered by Cummins ISC engines and Allison B400R5 transmissions, the major difference with this order were the destination signs. After having numerous visibility issues with the earlier Balios signs, ETS decided to try the Luminator Horizon orange LED sign system instead. This was the same type of sign demoed in #209 the previous year. The other spotting difference for this order is the front seating; the rear facing wheelchair position was deleted in favour of the earlier 3 + 3 dual forward facing layout. Almost all of these buses had their interiors updated with blue ETS insignia seat inserts. Many also had Cummins ISL engines installed in place of the original ISC. All buses received Smartbus GPS & stop announcement systems in 2016, and interior and exterior camera retrofits in 2019. At the onset of the Covid-19 Pandemic in March of 2020, 4301-4303, 4305-06, and 4309 were parked and did not reenter service. All remaining units were refitted with operator shields and reentered service by September 2020. They were also refitted with operator's compartment A/C units (minus 4304 and 4329 which ran without A/C until retirement in May-June 2022) and smart card readers for the ARC fare system in 2021. Because these are the oldest buses to have received this system, in anticipation of their retirement, many have since had one of the two rear door card readers removed and donated to other, newer buses. 4307, 4329, and 4349 were sold to Sunshine Village Ski Resort as their #37, 38, and 39 in mid-2022. As of November 2023, all of these buses are in active service minus #'s 4301-07, 4309, 4321, 4323, 4329, 4332, 4349, and 4351.
