This project seeks to define the performance requirements for a wireless Digital Train Line (WiDTL) through definition of functionality and performance expected, and translating these into network equipment specifications and architecture that wireless network equipment manufacturers can build towards. The effort will include an in-depth review of wireless technology as it applies to sensitive and vital communications, and also an evaluation of the commercial technology available to meet the needs outlined.

The Next Generation Equipment Committee (NGEC) developed a standard for specifying the use of an Ethernet based digital train line (DTL) network to replace the COMM line for passenger trains. These specifications are PRIIA 305?919 Digital Train Line Hardware and PRIIA 305?920 Digital Train Line Software. The intent Is to eventually allow for the improvement of passenger train control. DTL specifies a need for a wireless DTL (WiDTL) network to be used as a redundancy or backup in the event an inter?car jumper connection fails.
