The first experimentally air-conditioned TDH-5105 visited Washington in the Summer of 1956. It was painted by GM in attractive two-tone green with orange flamingo striping and white roof. Claire Clark, a wife of Roy Chalk, President of D.C. Transit, liked the livery and it was choosed as new company's livery. Also, an order for 67 air-conditioned TDH-5105s was placed with GM Coach and the order was delivered in July 1958. The coaches were numbered into 5600-5666 series and were placed on D.C. Transit's busiest routes. They had modified rear windows and wore "Arcticooler" and "Air Conditioned" lettering.
