This project aims to observe how a railway user of the middle of the 19th century could travel between some cities such as Paris, Lyon, Geneva or Marseille in regards to nowadays. Several aspects of the trip have been looked into, the journey path, the schedules of the trains and the price of the tickets. All of these informations come from a single document that contains both a timetable and a map of the railway network and have been computed into a program, so one can look for a trip and find easily all the informations needed. This whole project puts into perspective how the evolution of transports, in this particular example trains, have made the world much more connected and travelling much easier.

The document

This project will focus on this old train schedules from 1858. It has been found in the Bibliothèque Nationale de France's (BNF) digital library, Gallica. This document belongs to BNF's department of maps and is in free access, as all the document presented in Gallica.

It has been made by Alfred Potiquet (1820-1883), a civil engineer known for being responsible of the first stamp catalogue in the world, in 1861. Its exact title is Chemin de fer de Lyon à Genève. Marche des trains depuis le 10 novembre 1858. Correspondances les chemins de fer de France, de Suisse & d'Italie. As the title implies, it contains the complete timetable for train between Lyon and Geneva, but also the connections between Swiss, French and Italian trains. It has been decided to focus the project on this last aspect, since it is more relevant for us to know how long it takes to go from Paris to Geneva than from Montluel to Bellegarde for example.

This document shows different possible paths between "important" cities, with detailed stops when the train is between Mâcon, Geneva and Lyon, as seen in the picture XXX. For each of this path, one can read the prices for each class (first, second and third), the distance between the destinations ad the different departure and arrival times. Some mental maths were required, as the prices and distances were always shown in regard to the first city of the path.

A few observations can be made on the document. First, some trains are written as "express" and are first-class only. Then, the schedules were based on a 12-hours format, with the indications of "matin" (=morning) and "soir" (=evening) to know if it is am or pm. However, these indications were not always clear and it can get quite confusing to know whether the train leaves in the morning or in the evening. Furthermore, some small incoherences were observed in the timetables, for example the distance is sometimes different if one goes from A to B or from B to A. Same goes with the prices. But these differences are usually not more than a couple of kilometers or a ten of cent.

Project Plan and Milestones

The first obvious thing that had to be done with such a document was understanding how it works, i.e. what informations it contains and how they are organized. The document was printed in an A3-format to facilitate its study and the manual data extraction. Then the main focus switched to the coding part of the project. Some basic knowledge in web languages (HTML, Javascript, JSON, CSS, ...) were essential for this project and one had thus to get first familiar with this language. Then, some Javascript library were identified as potentially helpful and the data were chosen to be entered in the computer as JSON objects. As this is a tedious job, It was decided to make a first test of the program with only one possible route, and then, only if it turned out to work well, to enter more data to extend the program. The feasibility of converting the data into GTFS (General Transit Feed Specification) format is currently being evaluated, as it seems that setting up a server to host node.js is the only way to use GTFS data, and it is not sure that we have the appropriate skills to do so. The aesthetic aspect of the interface and the completion of the wiki article were dealt at the end of the project, when the program was fully working. All these tasks were evenly splitted in order for each member of the group to spend the same amount of time on the project. Weekly meeting, in addition to the usual lecture hours were set up to insure that the project was going forward and respected the milestones set at the beginning of the project. The following list summarizes how the project was planned:

Already done:

• 12.10.2018: Formation of group, choice of map.
• 17.10.2018: Decision about what to do with this map. Resulted in a CFF-like website.
• 19.10.2018: Presentation of the idea to the class.
• 24.10.2018: Understanding of the document, A3-model printed.
• 31.10.2018: Getting familiar with web languages. Basic HTML program. Choice of system to store the data (JSON file).
• 07.11.2018: Preparation of the slides for the midterm evaluation. Choice of java libraries for the program.
• 09.11.2018: Mid-term presentation.

Plan for coming weeks:

• 28.11.2018: Working program with one route only (Paris - Bourg).
• 28.11.2018: Half of the data (recto of the page).
• 12.12.2018: Full set of data.
• 12.12.2018: Aesthetic aspect (CSS file).
• 14.12.2018: Wiki article.
