The initial investigation indicated that the 2004, IC, 77 passenger bus, which was driven by John Stevens, 78, of Mabank, was southbound on Cream Level Road as it approached the railroad crossing. The bus came to a stop but then continued across the tracks, directly in front of the westbound Union Pacific train. The bus was impacted on its left side and became lodged on the locomotive. The train and bus then traveled approximately one quarter of a mile down the track before coming to a stop at the Murchison Street crossing.
