"The story is this, after visiting the C.P. road engine shop, for a picture of a SW10 in CP colours (ex UP) crossing the overpass in front of the Alyth yards, I notice what looked like a yellow locomotive behind a CP ready to leave, (I initially thought it was a SD40 in UP colours but with red CP Rail painted on, anyway when we got to it and realised it was unusual to say the least, Alaska Rail, a double stack had just entered the yard passing through to the intermodel facility, as we sat there I suddenly noticed the CP/AR train was suddenly moving, the result was those pictures in 3 locales."
