An 89-year-old train depot in Alton is being razed. Union Pacific had been leasing the building to Amtrak . The passenger rail service started serving passengers at the new Alton Regional Multi-Modal Transportation Center in September. A demolition team began earlier this week by punching a hole in the wall of the building. That allowed benches to be moved out of the interior before machinery proceeded. Union Pacific did not want the 1,600-square-foot building to be used for another purpose because of how close it is to railroad tracks. The company feared liability issues as a result.
