Batman stores all of his technology beneath Wayne Manor in what is called the BatCave. The cavern system beneath Waynne Manor is quite extensive and has not been completely mapped. It did have a connection to the Gotham Subway System and Batman had a high speed railcar that once used that connection to get into Gotham. Batman's information technology is located in the Batcave as well. All of Batman's data is highly encrypted and secure. Besides, Batman, Tim, Alfred and Oracle are the only people with complete access to the Batcave computers. These computers have Batman's criminal database and his connections to other information resources. The cave also keeps what little memorabilia that Batman deems important enough to save.
