Streamlined Ka

Streamlined Ka. Designed off the recent K model with the shroud based on when they first entered service.

Following the success of the K class, there was a need for more similar locomotives in the North Island. The new locomotives incorporated a number of improvements, including a re-designed plate frame to eliminate the cracking issues the K class were experiencing; roller bearings on all wheels; hydrostatic lubrication throughout; and the inclusion of the ACFI feedwater heater system as pioneered by K 919. As the ACFI equipment was criticised for its aesthetic appearance, it was obscured with shrouding fitted to both the K^A class and contemporary K^B class.
