With the Cascade Range to the north and the Green River to the south, Weston was disadvantageously located for future expansion. In 1891-2, the Northern Pacific moved its western helper terminus approximately four miles to the west at a point it designated Lester, Washington. Weston was unique in that the Northern Pacific, crossing the Green River twice, also created a short cut-off line at Weston, creating a complete loop. (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.)
