This is another of my escapades with Valkyrie, i.e. the trike. It was February, 2010. I was out riding on the levee before work, and down on the road was a long, long line of cars, just sitting there. They couldn't go anywhere because of a train.
It was delightful to be able to ride on past them all. After the bike path came down to where it runs alongside the foot of the levee, I was right alongside the tracks (tracks on one side, levee on the other) -- and the train. I put on the steam, PASSED the train, and beat it to the crossing where I leave the bike path. I had a block or two to spare, too.
If I remember correctly, I was going 10-12 mph. That was a very hard effort at the time, especially as I didn't yet have the three-speed hub; and beating the train was quite satisfying.
