aikataulukirja

An aikataulukirja, which translates to "timetable book" or "schedule book" in English, is a printed publication containing railway timetables. Historically, these books were essential for both railway operators and passengers, detailing train schedules, routes, station stops, and sometimes even platform information. Before the widespread adoption of digital travel planning and real-time information systems, aikataulukirjat were the primary resource for understanding train travel.

These books often covered extensive networks, sometimes national or even international, and were updated periodically to reflect changes in schedules, new lines, or operational adjustments. They were typically produced by the railway companies themselves or by specialized publishers. The format of an aikataulukirja was usually a bound volume, with pages organized by route or by time of day, presenting the information in a structured, tabular format.

For passengers, consulting an aikataulukirja allowed them to plan journeys, determine departure and arrival times, and make connections. For railway personnel, it served as an operational guide. While their importance has diminished with the rise of digital technology, aikataulukirjat remain a significant part of railway history, offering valuable insights into past transportation systems and the evolution of travel information. Some collectors and railway enthusiasts still find them of interest.
