WP 7209 at Lucknow A total of 755 of these stylish WP class broad gauge pacifics were built for the Indian Railways between 1947 and 1967. Unfortunately they never reached the heady speeds suggested by their streamlining. WP 7209 was one of the initial prototype batch of 15 locomotives built by the Baldwin Locomotive Works in 1947 and was still going strong when photographed on the Northern Railway at Lucknow in November 1978.
