In the early 1980s, nearly 100 years later, the Burlington Northern Railroad (BN) merged and bought all of the Frisco.
After the merger the Avard Sub and all of its 100 years of existence, was track warrant control (TWC).
Then in 2012, BNSF signed an agreement with Asian markets to have containers back in Asia (China, Japan, Korea, Vietnam, etc.
In February 2018, BNSF announced their intention to add a new siding to the Avard Sub near Hopeton, OK.[1] The work was completed by Millstone Weber in August 2018.
Intermodals are good to run 70 mph, however there are a lot of permanent speed restrictions across the Avard.
