TRANSCRIBER'S NOTE
Obvious typographical errors and punctuation errors have been corrected after careful comparison with other occurrences within the text and consultation of external sources.
Basic fractions are displayed as ½ ¼ ¾; other fraction are shown in the form a/b as 1/117 or 392/10 for example.
A large dense table spanning two pages in the original book ([page 158 and 159]) has been split into 4 parts, with column #1 (engine number) being repeated in each part. The vertical column headings have been replaced by a key, A B etc, with an explanation of the keys at the beginning of each part. Some cell values were unclear in the scanned image and a best guess of the digit has been made.
Another large table at [page 447] has been split into 2 parts.
In several tables with dollar.cent values the decimal point is faint or missing. For consistency the decimal point has been inserted in all cases.
[Footnote #31] had no anchor; this has been added in the chapter title.
Two illustrations and their captions were placed sideways in the original book at pages 87 and 97. These are displayed normally (horizontally) in the etext at [pages 86] and [96].
Nine consecutive full-page illustrations placed after [page 428] have detailed maps and Gantt charts and many have large amounts of text on them. Most of this text, and the Gantt chart information, have been copied and placed under the illustration in a dotted-line box. If the image is clicked, a larger version of the image is shown.
In the organization chart on [page 185], it is very likely that the Train Master and the Station Agents were all intended to report to the Superintendant of Transportation. The missing connecting line has been inserted using a dotted line to indicate this insertion.
