Summary: | Snow accumulations have been observed on a number of different shaped beams that may be employed for guided air cushion train tracks. At low wind velocities the snowfall accumulation was similar on all horizontal surfaces; however at high wind velocities the beams with a plane upper horizontal surface accumulated much lower quantities of snow. The vertical member of the inverted Tee track acts as a 100% density snow fence for snowfall with a crosswind. (Author) |
