The resulting account, in Chapter 9, of the Cheynes' journey from San Diego to Boston, is a classic of railway literature. The couple travel in the Cheynes' private rail car, the "Constance", and are taken from San Diego to Chicago as a special train, hauled by sixteen locomotives in succession. It takes precedence over 177 other trains. "Two and one-half minutes would be allowed for changing engines; three for watering and two for coaling". The "Constance" is attached to the scheduled express "New York Limited" to Buffalo, New York and then transferred to the New York Central for the trip across the state to Albany. Switched to the Boston and Albany Railroad, the Cheynes complete the trip to Boston in their private car, with the entire cross-country run taking 87 hours 35 minutes.
