Santa Fe owned two types of Burro cranes, the type 30 and the type 40. Type 30's had the pulleys for the boom arm located on the roof, while the Type 40's, such as this one had pulleys located in front of the cab. The cranes were named for a popular pack animal in the Southwest United States, the burro. BN 975048 has been stored at the MOW siding at Winton, stripped of its boom, which is now used as a spare for another crane located at the wye at Merritt. Since 2007, this crane has been used for MOW work on BNSF's Scenic subdivision from Seattle, WA to Wenatchee, WA.
