The cross-section on page 1177 illustrates the details ofthe track foundations, while the appearance of the work atvarious stages is shown in several half-tones. One of thelatter is of particular interest as it shows the track com-pleted on one side, different foundation layers on the otherside and the 10-ton steam roller, which was used to rollthe subgrade as well as theballast.
