Amtrak could save at least $23.2 million in unnecessary costs and realize as much as $6.8 million in additional revenue if it does a more effective job at managing its real estate, according to a new report by Amtrak's Office of Inspector General (OIG).The OIG identified "several opportunities to strengthen the effectiveness" of Amtrak's real estate property management process, including by using better data and analytic tools to make decisions about the properties. The OIG recommended that Amtrak finalize plans and develop a timeline for collecting quality data.
