Thanks a lot for your elaborate explanation, Henri ! 🙂
Your development method isn’t that different from mine only i use trains instead of buses to connect cities. I did find that setting up bus and tram lines first in the cities i initially want to connect, wait and see what they do and only then connect the cities via railway. I was curious to find out about your bus city connection so i tried that with immidiate success. People couldn’t wait to hop these (6) buses ! 😉 Mind you, this bus line went to a city which wasn’t connected by railway just yet. I will certainly use this method in my next endeavour.
Thanks much again for this tip and explanation. It certainly is helpful !!
