Cold crude loads?

[NWCanuck]

I was working in a high rise apartment today on the tenth floor that over looks the CP mainline going into London, ON heading east. Caught a glimpse of a crude train going buy and noticed something odd about the cars. Seems that the cold temps over the past few days which have been on a three day average of -20 Degrees Celsius has cooled the loads down enough to cause Ice to form on the outside of the tankers. We have had an overnight temperature rise from -20 to plus 3 degrees celsius with light drizzle and fog today. Makes it easy to see how much cargo is in each tanker! Just wish I could have gotten down to the main floor for a clearer picture. This shot was taken from the tenth floor through a dirty window near sunset and overcast. Sorry.

Actually I think the loads are warmer than the outside temperature which causes moisture to condensate at the level of the oil.
Cool effect to model if you have a winter scene, which I plan on doing....
We're finally out of our cold snap here, thank goodness!
