Whilst blasting around Berlin today I was faced with a bit of a dilemma. I had one change which could be accomplished in two ways in exactly the same amount of time:
1) Double back one station, change to overground, two overground stops
2) Direct bus
I made the wrong choice (bus) and lost about 10mins owing to the bus not turning up.
Seeing as trains are generally more reliable, I was wondering:
How much time would you have to save by going by bus to choose it out of a train/bus choice?
