>>1579147>A good historical one is Rollins Pass.I used to live near Rollins Pass and it’s an awesome drive to the top on the old grade, tooth rattling in a 2wd car but it’s doable. I’ve only drives up the east side and you can’t go all the way with the collapsed Needle’s Eye tunnel. Rollins Pass was sick, with 4% grades over an 11, 000’ pass, not to mention the snow. I’ve seen photos of quadruple header steam locos pushing a rotary snowplow.
