Shipping Alberta bitumen to Alaska in railroad tanker cars is a STUPID IDEA for many reasons...

Bitumen rail-tankers cannot haul anything back to Alberta.
If bitumen is to be hauled to Alaska it should be hauled as solid block bitumen on flatcars so we can use the flatcars to haul back intermodal container freight to L48.

BigOil in Canada is just as stupid as it's goofy operations in AK-NSloppy & worldwide CRUDE behavior, causing wars and terrorism endlessly.
BigOil wastes mega-energy trying to separate the sand from the bitumen.
A plasma-gasifier can efficiently process the raw tarsands to produce two feedstock product streams;  hydrocarbon alkanes & silicon silanes.

Why are SILANES more valuable than hydrocarbons ??

AOGCC is stupid
plasma-gasification renders BungledPlumbing's CGF-Prudhoe obsolete.
We had the technology in 1970 to gasify all of Alaska's hydrocarbon
