I was stopped by A&M railroad doing some switching in their "North Yard" in Springdale Arkansas. I had a Front Row Seat, just the thing for a "train nut" But waiting 15 minutes for A&M to 
switch the yard was making the drivers behind me go NUTS.
A&M was switching with their new SD70ace locomotives. The crew had just made up the longest train that I have seen on the A&M (approx 50 cars) made up of mostly sand cars and had backed up this long train to get the crew member that was working the switches in the yard, and clear the road crossing.
