[14] OmniTRAX purchased the abandoned Western Electric Hawthorne Works in Cicero, which was adjacent to the Manufacturers' Junction Railway, and began developing it as a multimodal transfer center.

[8] In October 1992, OmniTRAX purchased 800 miles (1,300 km) of track in Kansas and Oklahoma from the Atchison, Topeka & Santa Fe Railway.

[18] OmniTRAX purchased 31 miles (50 km) of track between Borger and Panhandle, Texas, from the Atchison, Topeka & Santa Fe in November 1993.

[19] Eighteen months later, in May 1995, OmniTRAX leased the 25.5-mile (41.0 km) Northern Ohio & Western Railway from the Sandusky County/Seneca County/Tiffin Port Authority.

[30] June 2014 also saw OmniTRAX purchase the Brownsville and Rio Grande International Railroad in Texas,[30] bringing its number of rail subsidiaries to 19.

[33] In the early months of the year, it spent $14 million restoring 7 miles (11 km) of track between Greeley and Windsor, Colorado.

The firm also proposed buying track owned by Warren County which ran from North Creek to Corinth, New York.

Local residents, concerned that OmniTRAX would permit its track to be used for the storage of oil tank cars, opposed the sale.

[36] In July 2019, OmniTRAX purchased the 100-mile (160 km) Winchester & Western Railroad's Virginia Division from Covia Holdings for $105 million.

[1] In 1997 the Canadian National Railway sold the Port of Churchill and accompanying rail line to OmniTRAX as part of the privatization of CN.

The company claimed that due to the closure of the Canadian Wheat Board in 2008, it was no longer economical to operate the line or the Port of Churchill.

In response, the company filed a complaint through NAFTA Chapter 11 claiming the Canadian Federal Government had sabotaged efforts to repair and transfer ownership of the railway.

[42] On August 31, 2018 the port and rail line were sold to Arctic Gateway Group, a consortium of investors including First Nations, local governments, financial holding companies, and grain producers.

[43] In 2003, OmniTRAX was one of three companies bidding for BC Rail, a 1,441-mile (2,319 km) province-owned railroad in British Columbia then being privatized by the government.

[44] Although the British Columbia Liberal Party had pledged during 2001 elections not to sell the road,[45] OmniTRAX officials continued to urge them to do so in 2002.

Pilothouse lobbyist Erik Bornmann bribed two ministerial aides from 2001 to 2003 with cash and gifts in exchange for confidential government documents that were then passed to OmniTRAX.

[48] Law enforcement officials never charged OmniTRAX with any wrongdoing in regards to the bribery effort or the receipt of stolen documents.

[49] OmniTRAX dropped out of the auction (police later alleged, based on wiretap information) after its officials came to believe that the provincial government had predetermined Canadian National Railway to be the successful bidder.

[51] OmniTRAX is subsidiary of The Broe Group, a company with an array of financial interests in energy development, healthcare technology, real estate, transportation, and other industries.

[53] In 1997, TSS won a contract to provide switching services at the newly-opened Deltaport, the Port of Vancouver's new container shipping facility.

In 2016, OLS purchased the assets of Terracor Group, a firm that provided ultra-fine-grain sand for hydraulic fracturing purposes.

The joint venture is marketing the Arrows Up Jumbo Bin, a container which can be used by rail or trucks that is capable of holding up to 25 short tons (23 t) of frac sand or ceramic material.
