CN Business Train

I've heard rumors that CN management painted two of the biz train engines (ex-BN E9's) back to traditional CN yellow/green. Any truth to this, and was it the CN-painted red/black units or the IC black/grey units? Is the entire business train going to follow?

I saw it in Montreal 2 weeks ago,it was leaded by a GP40-2w and composed of two green and black passenger cars

it's not my picture,but I put a link to see it directctly on the author flickr page

I drove by Woodcrest Shops today and saw that one of the business kept outside was painted in the traditional CN colors as pictured above. The other was still in Illinois Central black and white.
CN is also building a rather dramatic office building on the Woodcrest property in Homewood, across the street from its existing U.S. headquarters.
