Located at the foot of the western 2.2 percent grade of the Northern Pacific Railway's climb up Stampede Pass to Stampede Tunnel, the town served as the western helper station on the pass, counterpart to Easton, Washington.

With the Cascade Range to the north and the Green River to the south, Weston was disadvantageously located for future expansion.

In c. 1891, the Northern Pacific moved its western helper terminus approximately four miles to the west at a point it designated Lester, Washington.

(Further to the east, approaching the summit of Stampede Pass, the Northern Pacific's engineers alignment created what came to be known as the Borup Loop [so named for the telegraph station located at the center of the loop—Borup, Washington], this however was a misnomer, as the alignment is actually an elongated S-curve created by back-to-back horseshoes.)

The image accompanying this article looks down from the trestle which crosses the Green River and replaced the old loop arrangement.
