The D&KR initially introduced four types of four wheeled carriages. The fully enclosed purple first class carriage had 3 compartments, each with two rows of upholstered seats seating three abreast. The pale yellow covered carriages also had upholstered seats in three compartments but at four abreast for a total of 24 passengers. The green second class open class carriages were only used in summer. They had open sides and a roof and seated 28 in seven rows. Blue third class carriages were understood to have had roofs despite the depictions of contemporary illustrations. Capacity per carriage was 35 in seven rows of five abreast on boarded seats with low backrests. Typical trains consists were a single first class carriage, two to four second class and three third class. Many carriages were converted to gauge in the mid 1850s.
