The Motor Coach Industries D4500CT is a commuter and charter motorcoach available in Canada and the United States. In 2005, MCI redesigned their D-Series coach. The D4500CT inherited the headlights from the G-Series and is available with optional flush-mounted passenger windows. Fluted stainless steel sides are also an option.
Long a fixture of commuter fleets across the country, the D4500CT is scheduled to be phased out at the end of the 2021 model year in favor of the new D45 CRT high floor commuter coach.
Design Changes
Coaches meeting the EPA 2007 and 2010 standards sport a redesigned rear end incorporating changes to the engine cooling system for each emission standard. Coaches meeting the EPA 2010 standards are also equipped with a selective catalytic reduction system that includes a 15 gallon diesel exhaust fluid tank.[1]
Likely as a request from New Jersey Transit, their 2014 batch of D4500CT coaches were delivered with redesigned headlights. This simplified design has three round LED clusters arranged in a gently curving row. Other operators, such as Broward County Transit and GO Transit have adopted the same headlights.
Alternative propulsion
A diesel-electric hybrid version of this coach, dubbed the D4500CTH, made its debut in 2007. Houston METRO was the launch customer.
In April 2010, MCI began touring a CNG-powered commuter coach. The coach was leased from New Jersey Transit and updated with a newer 8.3 litre Cummins CNG engine. In addition, a new coach was built with an 8.9 litre EPA 2010-compliant Cummins CNG engine and shown to multiple transit agencies. MCI wanted to gauge the market for the coach and show off the benefits of CNG.[2] The tour ended a few moths later, and in October, MCI announced a CNG power option will be available on 2011 coaches.[3]
