This collection of Penn Central employee timetables, assembled by Henry Frick of Fort Worth, has the advantage of being a complete set covering the company's contraction and decline.

Employee timetables differ from those prepared for the public in showing freight as well as passenger service and the times at which trains pass various checkpoints. They also contain special instructions for train crews concerning the operation of trains. For example, they note "slow orders" where speed limits were reduced to as little as 5 or 10 miles per hour because of track the company could not afford to maintain. About a third of the timetables have the pasted-in supplements and general orders issued to cover changes in service and operating conditions that would accumulate before an entire timetable was reissued. These permit following the increasing restrictions, line abandonments and rearrangement of operating divisions and regions, as management and the trustees sought to cope by paring away redundant lines and unremunerative services.
