North American freight train fans! Locomotive ID?

Question

Near Hamilton, Canada I saw a triple header freight on a CP track One of the engines was sky blue(turquoise?) on the front and side of the cab with an orange stripe (horizontal rectangle; maybe a logo) on the engine part It was far away and very grungy (disconiued scheme or defunct rail line?) I am pretty sure it was NOT a CSX locomotive. I see freight from all over the USA and Canada here, though. Any ideas??

Answer 1

Could have been an old Conrail unit, though I don't believe I ever saw any with an orange stripe.

Some leasing companies have added their own touch to the older locomotives they acquire before putting them into leasing service.

A demonstrator model is also a possibility.
