These videos were presented at the Board meeting on 7/21/99 in Washington, D.C.
The animation clips depict the last 60 seconds of motion for the Northern Indiana Commuter Transport District (NICTD) two car passenger train which struck the second semitrailer of a long combination vehicle (LCV) that consisted of a tractor pulling two flatbed semitrailers loaded with steel coils at the Midwest Steel Plant highway-rail grade crossing near Portage, Indiania. The position of the truck with trailers, recorded speeds for the NICTD commuter train, NICTD train's brake application, the operation of the grade crossing gates and signals, and the motion of a Conrail freight train operating on an adjacent track and going in the same direction, are also shown in the animation. Three segments of the animation are represented, a panning view, signals view and overhead view.
