An interface adapter is provided between the locomotive MU cable and the ECP trainline permitting ECP data from the lead locomotive to be transmitted via the MU cable on trailing locomotives to a train of ECP cars.

Why it's free to use
- Filed November 23, 1999 and granted March 11, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 23, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 23, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
