Arlington P25 Trunked System in Metro Tunnels

Arlington County has apparently installed the equipment to allow their Project 25 trunked system to broadcast in the Metrorail tunnels. It is up and running in at least the Clarendon, Court House, and Rosslyn stations and the tunnels in between. Previously, they had a single 800 MHz conventional repeater for fire (856.4875) and police (858.4875). These frequencies appear to still be in place.
