>>1876845Bus 27 connects Wilchingen and Hallau to the Wilchingen-Hallau station that lies pretty much in the middle of the two towns. It's a feeder line, timed to arrive 3 minutes before the train that runs to Schaffhausen. However if you want to take the train in the other direction (albeit there's just two more stops, although the last stop connects to long-distance trains), then you have to wait 13 minutes, which will likely mean that for a trip from Hallau to Trasadingen you'll spend mire time waiting than travelling.
