The document summarizes changes made to simplify and shorten the railway rule book. It discusses how a review found that many existing rules were duplicated, not applicable nationwide, or specific to one company. The new rule book has been reorganized into 32 modules and 19 handbooks instead of the original 48 modules. It has reduced the total page count from 1,820 to 1,108 pages. For example, the rules for basic track workers have been reduced from 115 pages to a single 20-page handbook. The changes are aimed to make the rules easier to use, understand and maintain.
