The town was named for former vice president of the Northern Pacific Railway, Daniel Lamont.

The terminal included a depot, yard, 22 stall roundhouse and locomotive servicing facilities.

But the railroad shortly reconsidered the remote outpost of Lamont as a terminal, and when the roundhouse burned in 1913, crews started working through between Pasco and Spokane.

Lamont contributed a healthy amount of traffic to the railroad in the form of grain and livestock over the years.

After the merger, the SP&S and NP lines between Pasco and Spokane were used like double track, with heavy lumber traffic running east over the easier grades of the former SP&S and westbound traffic on the former NP.

Following the bad recession of the early 1980s, BN began to look at ways to reduce the amount of its track in Washington State.

In the mid 1980s, BN upgraded the former NP between Spokane and Pasco and moved all the through trains off the former SP&S in 1987.

In 1991 the track was removed and the State of Washington obtained the former railroad line as a trail.
