Herrin Transportation Company

In 1932, Robert, O.B., and C.G. Herrin formed Herrin Transportation Company with initial service between
Herrin would grow to operate more than a thousand pieces of equipment (237 tractors, 548 trailers, and 219
straight trucks) out of their 21 terminals. Their authority covered Arkansas, Florida, Georgia, Louisiana,
Tennessee, and Texas.

Herrin’s original equipment was a “slightly used” three-contractor, then a ton and a half and a two-ton truck
pulling a tarp-covered semi. It was a good thing that the load limit in Texas was 7,000 pounds because it is
doubtful that their tired equipment would have been able to pull more than that.

IML FREIGHT, INC.
SALT LAKE CITY, UT

Starting from a one-man, one-truck operation in 1929, IML Freight eventually grew to more than 2,000 units
before ending operations in 1984.

Thomas S. Carter began his trucking company in Salt Lake City and eventually watched it grow to an operation
with 35 terminals covering the country with direct service to 25 states.

At its peak the IML fleet, consisting mostly of White Freightliners, was one of the busiest in the country. It
handled 1.5 million shipments and rolled up 43 million miles in 1964, most of them through the rugged Rocky
Mountain states.

In 1983, IML filed Chapter 11 bankruptcy proceedings and began cutting back operations by closing its eastern
terminals. However, freight continued to move through an interline arrangement with Central Freight Lines of
Michigan and Mason-Dixon in Tennessee.

A systematic shutdown gradually followed for the next year until IML closed its doors for good in March of 1984,
just two days after being struck by the Teamsters union
