Manteca is on track to be impacted by high speed rail.Andrew Chesley is sure of it.“High speed rail makes sense for California,” the executive director of the San Joaquin Council of Governments told Manteca Rotarians recently during a meeting at Ernie’s restaurant.Often dubbed “The Crossroads of California”, Manteca may become the only city in the state that eventually is at the crossroads of high speed rail.Two of three high speed routes that ultimately will connect Sacramento with Los Angeles could impact Manteca. Then there is the Altamont Corridor Express that is authorized under language in the bonds approved by state voters to compete for high speed rail funding for the Bay Area to connect with Merced and Sacramento.Chesley expects the process of determining the exact route for high speed rail in the Manteca area won’t get underway until at least 2025.The three routes are:ufollowing Union Pacific Railroad’s existing corridor through Manteca. Typically in urban areas high speed planners are calling for putting the trains in “trenches” such as has been done in downtown Reno for heavy rail.uskirting the eastern edge of Manteca roughly a half mile or so east of Austin Road.ufollowing the Santa Fe Railroad line through Escalon.
