However, the plan used was virtually identical to that used at Fairbury, including the street names, and very similar to that used at Gridley, El Paso and other places along the Peoria and Oquawka Railroad. This suggests that the railroad supplied the plan from which Buck worked. Like these other towns, Chatsworth was centered on a long narrow depot grounds rather than a public square. The plat of the original town was exceptionally large, covering and consisting of 42 blocks, most located north of the railroad. The early depot was on the south side of the tracks. Block 16 of the plat was not divided into lots, and 1878 was listed as the City Park. It was
