From "Northwest Railfan."
The winter storms that hit the Northwest over the holidays gave BN many weather related problems.
The Interbay rotary snowplow #972651 (ex-GN #X-1510 built 1927 by Brooks) was called out to plow massive snowdrifts on the CW Sub on January 11. This was the first time the Interbay rotary had been used since the mid-1970s. A spreader had plowed most of the CW Sub on January 8 but was unable to contend with huge snowdrifts in the Hartline/Coulee City area, prompting BN to bring out the rotary.
