BNSF Warbonnet 729 trails 2 out of 2 on a northbound Stack Train in Norman. This Train was the next train we saw after seeing EMDX 7226 on a northbound flatcar train. This Train stopped and waited for a Mixed Freight to pull into the siding. Then it started moving and went by the Mixed Freight. After the Stack Train passed the Mixed Freight pulled out of the siding and went by.
