According to rumours and leaks, the Niddertahlbahn is the forthcoming German route. Reading the Wikipedia article, there seems to be nothing remarkable about this line. It is a random branch line that is only 19 miles long, going against the supposed change of direction towards longer routes and doesn’t connect anywhere of importance or interest (with apologies to any readers who live along this line), unless maybe it’s extended to Frankfurt. Also, it’s a single line so there will be little or no scope for AI traffic. So what’s the reasoning behind releasing this route?
