Special Instructions Structure Example

Notes

The Special Instruction numbers listed in this PRR example are based on PRR rule numbers (which followed the AAR numbering scheme). Special Instructions are numbered 1000 plus the relevant rule number. Some Special Instructions receive numbers that correspond to unused rule numbers. For the PRR and other books of rules, see the FAQ.

Special Instruction examples below are taken from the 1967 Western Region PRR ETT. Passenger train content, for this region, at this point in history, was low.


The timetable proper runs to p. 44, then pp. 45-7 are Ticket Offices Open for Sale of Tickets; p. 48 is US Mail Work; pp. 49-53 are Arranged Freight Train Service (i.e., scheduled trains -- nowadays usually published separately, for information of shippers, and not in the ETT). Then the Special Instructions really start.
