CN's SD40s

CN had 241 SD40s built by GMD in London Ontario between 1967 & 1971 (other divisions had SD40s built by EMD). All unrebuilt units were off roster by 2006 though many rebuilt continued to operate (see other videos).
Only 30 were equipped with dynamic brakes and had the characteristic "blisters" on each side of the long hood. These units were numbered 5000 - 5007 & 5111-5132.
They are seen at work in both Western & Eastern Canada.
