I thought it would be a good idea to create a thread where people could post links to various resources that can be used to aid with timetable creation. I'm sure most people are already aware, but for the UK Network Rail have their working timetables online: Current Network Rail WTT https://www.networkrail.co.uk/running-the-railway/the-timetable/working-timetable/ Past Network Rail WTT https://history.networkrail.co.uk/uncategorized/SO_4b13306b-816a-4d77-89ec-630d6beb2680/
Timetables, train formations and a wealth of other data for German long distance trains past and present fernbahn.de/datenbank
Vagonweb is very useful for past and present train formations https://www.vagonweb.cz/ Current arrivals/departures in Germany/Austria, also shows formations (have to enable it in settings) https://bahn.expert/
