Amtrak passengers who’re crossing the nation on the “California Zephyr” were greeted with treats today at five Iowa stops. The celebration will be repeated tonight on the train’s return trip. Members of the Iowa Association of Railroad Passengers are marking the 30th anniversary of Amtrak at stops in Burlington, Mount Pleasant, Ottumwa, Osceola and Creston.Henry Wulff, the association’s president, says the Zephyr went east through Iowa this morning on its way from San Francisco and Denver to Chicago. It’ll go west this evening, making the same stops in Iowa, and the train will again be greeted by groups at five Iowa stops.Wulff says his organization wants to show its support for Amtrak, which went into service on May 1st, 1971, and now serves more than 22-million people a year, traveling into 45 states along 22-thousand miles of track. Wulff wants to see more trains chugging through the Hawkeye State.Proposals call for a new mail and express train to go from Des Moines to Chicago while another high-speed train could go from Omaha to Chicago with stops in Des Moines, Grinnell, Iowa City and Davenport. The Zephyr is slated to make stops tonight in Burlington at 6:59, Mount Pleasant at 7:31, Ottumwa at 8:24, Osceola at 9:40 and in Creston at 10:12.
