CN Craik sub

In theory, CN's Craik sub should be one of the busiest in the province, being the main link between Saskatoon and Regina, the two largest cities. Furthermore it forms a much longer North/South line, connecting Prince Albert to the US. Border (365.2 miles). It is so strait, that the main North/South HWY simply runs next to it. Here-in lies the problem.
The US. border-Saskatoon portion will soon be torn up (Craik+Lewvan subs), while most of the line to Prince Albert has been sold to a shortline, CTRW. CN wants to keep the Saskatoon-Davidson portion of the Craik sub, where a wayfreight runs to a grain terminal.
Then there's this piece on the other end. About a mile in Regina, used as storage for about a dozen hoppers and ~40 '89 flats. Sadly today these are the only cars left on the line (Davidson was empty) - no worries about blocking the mainline, a train hasn't run between Regina and Saskatoon since 2002.

Ironically CP's line between th two cities, which is not strait at all (176 vs. 154 miles), sees a fair amout of traffic (~3 trains per day), including this IMS wayfreight: http://tinyurl.com/28o3rt
and US bound unit potash trains. Now why coudn't CN run such traffic? CN still handles Intermodal between the two cities, via the HWY.
