All very good advise. Follow it. But....
Still, be ready to go down.
I routinely cross tracks on my rides. I don't like them, but I has become comfortable crossing them until....
I did everything by the book. Yet, while crossing tracks in the rain last year (during my first century), my rear wheel stepped out. Way out!
I nearly went down. It was an act of God that saved me. Not riding skill. With the vehicles behind me, it would have been ugly.
The slide out and resulting snap back was so harsh, it threw one of my water bottles out.
Although I bet it looked like a sweet bike trick to the people behind me, I nearly messed myself. After gathering my bottle, I stood in the rain near the tracks, trying to figure what went wrong.
Just be ready. You never know. Even the greatest plans fail on occasions.
Safe riding to you.
