How do the Amish, Mennonites, Quakers and the like along with the non-tech savvy or those with no access to the Internet fly without printed timetables? In fact as has been noted earlier, many airlines don't even have downloadable timetables. Those folks find a way to travel by plane without any problems.
Quakers? There may be a few meeting houses or groups who might be connected to the Society of Friends that reject modern technology, but Quakers as a group live in the modern world. Quakers are an entirely different religion and cultural group from the Amish and Mennonites, don't mix them.
As for Amish and Mennonites that don't use modern technology or electricity at home, there is the greater question of how they will be able to travel, shop, and interact with the modern world as it moves increasingly on-line and to computers. Everything from paying taxes & bills, buying goods or property, filling out government documents, travel by bus or train. Amtrak moving the system timetable to a PDF version only is just a small part of a long term shift to moving away from paper documents, forms, and tickets to all electronic formats.
I was in DC Union Station several months ago, exiting from the Metro station. I stopped by a fare vending machine in the Metro station to add a few bucks to my Smartrip card and saw what appeared to be an Amish family or group looking at one of the fare machines trying to figure it out. They looked to be at a lost. To be fair, that is a common response of tourists when they try to use the Metro vending machines for the first time with the bewildering table of station to station fares at the top, instructions all over the front, and the limited display and interface. But the Amish family looked to be totally lost. They had presumably arrived on Amtrak and were going to visit someplace in DC. I thought about trying to help them, but I had to catch an Amtrak train. I hope they were able to get assistance from the Metro station attendant or another passerby on how to buy Smartrip cards (with cash) and navigate the Metro system.
In an age where the modern world is increasingly moving to a cashless system except for small purchases, to smart phones, navigation apps, and the internet, how are the Amish, Mennonites, and people that don't use modern technology, going to be able to travel or deal with the rest of the world in 10, 20, 30 years? Going to be ever more difficult.
