"The carabas was a public car in the shape of a long cage, with capacity for twenty people. The carabas took four and a half hours to get to Versailles, for a fare of twenty-five pence." - Official Journal of April 29, 1875. Model: Maurice Leloir. Photo: Michel Urtado.
First, there was indeed transit before the 1890s. Burleson and Edward Erfurt are probably thinking of the first trolleys, autobuses and underground railways, which were implemented around that time. But before then there were other ways of getting around. On the StrongTowns podcast page, Steve commented that waterways - rivers and canals - provided a transit function.
Beyond the waterways, there were horsecars. These were large, horse-drawn vehicles that ran on rails, and could carry twenty or more people at a time. These began to appear in the early nineteenth century. The London Underground ran on steam from 1863.
Mike Lydon was the only one who didn't suffer from persistent transportation myopia. Burleson said, "Imagine a European-scale city that had no transit, but also had no cars." Transit and cars - along with taxis, hansom cabs and personal horse-drawn carriages - are different ways of enabling long-distance commutes. Transit is a long-distance commuting option that is accessible to lower classes.
Cities did exist for millennia, but it's worth noting that until the nineteenth century, they were small enough that you could walk from any part of them to almost any other part within an hour. So as Erfurt observed, transit allowed cities to expand beyond that size, but so did personal vehicles. Ian Rasmussen pointed out that transit opened the city to all.
An interesting example that proves the rule is Versailles. By moving the court a long distance from Paris, Louis XIV essentially split the capital over a distance of twelve miles. To compensate for that distance, a public transit system - the "carabas" - was implemented. It covered that distance in six and a half hours at first, but by the beginning of the nineteenth century it took only two hours, and there were twenty-six round trips per day. It was not the first transit system in the Paris region - Bibliophile Jacob tells us that in the late seventeenth and eighteenth centuries there was a whole network of public coach routes linking the various suburban palaces, with the frequency adjusted to the whereabouts of the King - but it was the best developed.
On one level, Erfurt and Burleson are right and you don't need transit to have a successful walking city. But you do need vehicle commuting to have a successful large city, and you need transit to do that equitably. I commend the debaters for what they were able to do within the constraints they had, and I thank them and the debate organizers for raising a number of interesting questions, and for recording the debate for posterity.
