Draft Standard


IEEE 1473-1999 is a published standard, available for purchase from the IEEE On-Line Store.

This standard is undergoing review for possible changes to include ethernet technology.

Upcoming Meetings:

There will be a meeting of RTVISC WG 1 on Tuesday June 5th, 2007 from 2:00 PM to 5: 00 PM in the Kent room of the Sheraton Center Toronto. The main topic of the meeting will be the proposal to include ETHERNET in IEEE 1473. Other topics can be given consideration to be added to the agenda if I am advised by May 15th 2007. Let me know if you plan on attending.

This standard defines the protocol for intercar and intracar serial data communications between subsystems aboard passenger trains. It sets forth the minimum acceptable parameters for a network that can simultaneously handle monitoring and control traffic from multiple systems. While the network itself is not vital, it is intended to be capable of carrying vital messages. This standard will be structured with respect to the OSI seven-layer model.
A standard protocol will permit systems provided by a variety of suppliers performing different on-board functions to share a common cummunications facility. Car wiring and weight will be reduced while systems integration, reliability, and maintainability will be improved.

Most Recent Standard

No new draft has been developed subsequent to publication in 1999.
