Since the first days of steel wheels on steel rails sand has been a necessity for good traction, and is still in general use today. Sand had to be stored and dried in facilities such as this Canadian Pacific standard sandhouse. This version was built from the early 1990?s (sic-1890s) and was still pumping sand into switchers in downtown Vancouver and Victoria BC into the mid 1990?s. Our model was measured from that facility. Along with the many regular Kanamodel features this kit also includes Grandt Line nut/bolt/washer castings, a simulated sand and gravel roof and a realistic cast sand pile that makes this kit an easy foreground model project and a necessity for any steam era layout. The footprint is 2 1/2" x 7"
